It’s actually depressing that I have to come back to these videos to learn. My college teacher doesn’t teach anything... At this point I had like four anxiety attacks while crying my eyes out and I have to go through this stressful process with the college’s assistant dean to try to fight for my grade. At least these videos take off some stress and prevent future anxiety attacks. Thank you.
Haaha same is the case with my college teachers they donot teach well and just try to cover the syllabus as fast as possible without even caring whether students have understood or not
Bro you- you- you are the absolute bestt broo. You explained so nicelyy i literally understood 2 whole lectures in 5 seconds .You are the best. I'm subscribing :) Btw, I'm in 9th :)
i seriously believe U DESERVE ALL MY MONEY BEC U BE GIVING US THIS LECTURES AND ITS AMAZINGGGG BECAUSE U CAN EXPLAIN IT EASILYYYYYYYY U ARE AMAZINGGGGGG
Thank you so much! My e book and the video in the e-book messed it up. They did not show rate1/rate 2 = sqrt (M2/M1) = T1/T2. It only contains rate1/rate 2 = sqrt (M2/M1) and it took me half an hour to figure it out. It wasted too much time for an easy problem.
No, the question was looking for the amount of time it takes for the gas to effuse, not the rate of effusion. The rate would have been higher, but the time it takes for neon to effuse is lower.
Helium consists of two isotopes 3He (natural abundance = 0.000134%) and 4He (natural abundance: 9.999866%). Their atomic masses are 3.01603 and 4.00260 a.m.u., respectively. Helium-3 has unique physical properties and is used in the study of ultralow temperatures. It is separated from the more abundant 4He by a process of gaseous effusion. Calculate the ratio of the effusion rates of 3He and 4He. how to solve this huhuhu
In the second problem, I am confused as to how he determined that O2 corresponded to R2. I thought since that was the information we were given in the problem it would correspond to R1. Why is O2 equal to R2 in the equation?
R stands for Rate (velocity) (speed). M stand for Molar mass. Thats just how you set up the equation so that each rate R matches with its molar mass M R1 matches with M1 and R2 matches with M2
Thank you so much for your videos! They've helped so much! P.S.: I am not sure if anyone has brought this to your attention. If not, in my chemistry book the equation I was given says R1/R2= the square root of M2/M1. I am curious if it makes a difference which of the two should be at the top.
If a balloon filled with oxygen gas took 5 hours to go flat, how long will it take a similar balloon full of hydrogen gas to go flat. Please calculate this
i really really really hope you answer this very simple question, please. how will you know which one among the 2 gas will be R1/ R2? can u please put a link on where i can find those practice test guides you were talking about at the end of the video please and thank you
thank you so much,,,, another thing,,, on the first sample problem. (argon and helium) helium has the subscript 2, was it because it has a smaller molar mass? i really really hope you can answer this.. thank you
It doesn't depend on the molar mass. You can set it up any way you want as long as the subscript matches. If R1 is assigned to Helium, than M1 should also be assigned to Helium. I hope that helps :)
Guys any help. The density of a gas of relative molecular mass 28 at a certain temperature is 0.90 kgm-3. The root mean square speed of the gas molecules at that temperature is 602 ms-1. Assuming that the rate of diffusion of a gas is inversely proportional to the square root of its density, calculate the density of the gas standard temperature and pressure if its root mean square speed at is 490 ms-1.
mind you that the problem is not about rate but it is Time. Rate and Molar mass are inversly proportional hence they are flipped in the equation, but time is directly proportional to molar mass, the heaviour the gas the longer it will take to refuse , hence time and Molar mass equation is not flipped as in the rate and Molar mass.
in the second example why did you multiply the molar mass of oxygen which is 16 by 2? It isn't 4? Since its 4 times faster? Need your response guys please

Stay safe kronos
Late but good luck. Try meditation to keep the mind healthy :D
same, im learning this in 10th grade and im literally so confused
@@sonyaharjani Bro same I barely have an A ;-;
this is my absolute favorite channel on yt... you are completely saving my gen chem grade
you are very beautiful
me too and u are beautiful
Studying for AP Chem midterms. Anyone else on an Organic Chemistry tutor binge?
🙋
Yup
My mans taught me more in 13 minutes than my chemistry teacher did in 1 year.
my chem prof tried to teach this in 10 minutes and failed miserably lmao
I could have payed attention in class but no
@O i was going to ask the same question buddy 😂😂😂
@O @Sandip Probably meant that his teacher just gives them work without explaining anything and hasn't taught any lessons.
Y E S
ty for saving my college gen chem grade bro i got an exam in about 2hrs 🙏🙏🙏
I can't stress how much you've helped me. THANK YOU!
Dude, I can't thank you enough, this cleared up so much for me
The time at 12:40 example is amazing, thanks!

You are a life saver, God bless you🤗
This is the only channel that helps me with these kinds of problem
Great video❣️ Love it
Thank you so much and God bless you, dear! You have been such a great help with this topic!
Great Explanation. College professor didn't even cover this in his lectures. Money wasted if you ask me.
How do I post a question and a reply to this brilliant tutor?
HIgh school teacher did not cover this at all 😐 but still felt the need to put 5 hw problems about it.
@@maddiedurkin1911 literally...
He has the knowledge in teaching 😂. Greatful thank you.

This guys actually so nice with math and science
For the third example did he switch the molar masses on accident or is there a rule im missing?
I'm wondering the same thing
No, the question was looking for the amount of time it takes for the gas to effuse, not the rate of effusion. The rate would have been higher, but the time it takes for neon to effuse is lower.
Thank you it really helps.
it helped me a lot thanks i was not able to work out any grahams law effusion
I really appreciate that.. thanks Mr .
My teacher really gave us two practice problems on this then made it 1/3 of the quiz. Test is tomorrow wish me luck
Thank you!!! This saved my grade.
MY SAVIOR i have an exam in an hour ty
this is very helpful
Thanks for this tutorial
This is great, but when I found this video after googling rate of effusion, the formula in your video's thumbnail appears to be wrong.
bruh you are doing the mos, like your videos are more than awesome .....thank you
Your video is very nice and helpful
Would you mind putting the questions a little lower so that it can show up when I pause?

thank you for this video, but why the molar mass of helium gas is 4 and not 8? because I thought helium gas=He2
exactly the same question I have
bruh its noble gas and they are always in mono atomic form .
Thanks for the helpful explanation
Dude thank youuu sooo muchhh like honestly your videos are actually really helpful! Thanks again
Well simplified bruh !
Ooooooooohhhhh! Thanks so much..a light bulb went off
Thank you for the help. I really appreciate it!
Watching this in y chemistry class because my teacher is ignoring me and my questions.
“Being absent is not an excuse for not knowing the lesson”
That's so bad! Nobody should be shamed for asking for help in school.
Thanks 👍👍
I appreciate
thanku so much.
thanks! this was great
so flipping both sides of the equation would still represent the same law right?
Ye
I think idk tho
In the second problem, I am confused as to how he determined that O2 corresponded to R2. I thought since that was the information we were given in the problem it would correspond to R1. Why is O2 equal to R2 in the equation?
R stands for Rate (velocity) (speed).
M stand for Molar mass.
Thats just how you set up the equation so that each rate R matches with its molar mass M
R1 matches with M1 and R2 matches with M2
Hows everything going now
can u give hard questions also for more practice
Is R1/R2 = square root of M2/M1 the same thing?
yes
yes it is
Dude saving my life lol.
Thank u so much
Mannnnnn thanksssss a ton!!❤️😭
Ok...it was fun ❤️❤️I had alot of fun from this tutorial. Much better than my chemistry teacher would do😍😍I understand everything perfectly fine
I had a fucking blast watching this tutorial man
This dude has taught me everything I know in chemistry. I love having a chemistry professor that doesn't speak good english...
do we always have to convert it in seconds to arrive at the answer? the problem i have in class has minutes
Is the third one incorrect? Don't you have to flip it so its inversely related? Just wondering!!
Can't help but think that the best analogy is someone farting in the classroom.
HAHA THX ILL REMEMBER THAT IN MY TEST TMRW
For question 2, how did he find out that the rate of effusion of oxygen is 1?
Thank you so much for your videos! They've helped so much!
P.S.: I am not sure if anyone has brought this to your attention. If not, in my chemistry book the equation I was given says R1/R2= the square root of M2/M1. I am curious if it makes a difference which of the two should be at the top.
Yes it does.
Dude: I will try to tell it simpler
The rate of diffusion(or effusion) of a gas is inversely proportional to the square root of its molecular weight
If a balloon filled with oxygen gas took 5 hours to go flat, how long will it take a similar balloon full of hydrogen gas to go flat. Please calculate this
Imagine having to learn gas laws and this in one week because your chemistry teacher is too busy with her niece who's a senior : )
Exceptional
i really really really hope you answer this very simple question, please. how will you know which one among the 2 gas will be R1/ R2? can u please put a link on where i can find those practice test guides you were talking about at the end of the video please and thank you

@@TheOrganicChemistryTutor thank you man
The law that we are using in our grade is r1 over r2 but whatever, is it always the bigger is r1?
pov your professor assigns you homework over things you never went over in class
Rate and density
this is the one thing that i didn't understand right away so far in my chem class lol
Explicit!!! Thanks
You're the best
Holy fuck I love this guy! Makes chemistry seem so easy!
I thought grahams law is for diffusion?
Can anyone explain?
Guys any help.
The density of a gas of relative molecular mass 28 at a certain temperature is 0.90 kgm-3. The root mean square speed of the gas molecules at that temperature is 602 ms-1. Assuming that the rate of diffusion of a gas is inversely proportional to the square root of its density, calculate the density of the gas standard temperature and pressure if its root mean square speed at is 490 ms-1.
Hi!
Can you confirm if kgm-3 is kg/m ^-3 or kg * m ^-3, and if ms-1 is m*s ^ -3 or m/s ^-3? Thank you.
Excellent
The more I watch your videos the more I think “JG on random stuff is starting to look pretty good”
Thank u soo muchhh !!!❤❤❤
thank you i wouldve failed my Chem quiz next block GOD BLESS
I just love you!!!
In the last example, you forgot to flip and put the M of Kr on the top.
mind you that the problem is not about rate but it is Time. Rate and Molar mass are inversly proportional hence they are flipped in the equation, but time is directly proportional to molar mass, the heaviour the gas the longer it will take to refuse , hence time and Molar mass equation is not flipped as in the rate and Molar mass.
+Sandile Skosana *effuse
*effuse not refuse
now is the tutor correct or not?
he's right
why do you use Big M for molar mass it looks like Molarity can you use mm instead or am i wrong
Thanks for the video. Please help. I don't understand why we are squaring everything
to cancel out the under root sign on the other side
I don't understand how to distinguish the difference between time and rate of effusion.
look at the unit for both entities. that should tell you the difference.
thank you
nice... but in my textbook they showed the relationship between rate of diffusion and density... so I was hoping to see dat
Mass and density are directly proportional. So they can be used interchangeably.
This is also effusion not diffusion
So does effusion and diffusion have the same inverse rule essentially?
How is the square root of 10 3.162
jo blackburn the square root of 9 is 3, so the square root of 10 should just be a little above that. 3.162 sounds about right
Can someone explain the relationship between Graham's law formula and volume please
My dream is to meet you in person someday 🥺.. I really love you ❤️🙌🥰🫂.... You make my academic life so very easy,I appreciate you so much 🥺
THANK YOU. HORY SHET. I KNOW NOW
in the second example why did you multiply the molar mass of oxygen which is 16 by 2? It isn't 4? Since its 4 times faster? Need your response guys please
It is because oxygen is a diatomic element.
Hahahaha yes thank you for responding.Got it!
Thanks a lot :)
what if its 0.5 as fast as carbon dioxide?? then its 1.5??
Hey how to relate the rate of diffusion of same or different gas at 2 different temperatures?
how do you know which mass to put on the top and which one on the bottom??
It doesn't matter as long as the rates are inverse with the masses
it's M2 on M1
DYK chemistry causes headache
hoping your videos will help me pass chem h jdhdnd
what if it has distance is it the same with the time thing?]
Good
guys I need help how do find the partial pressure using this law
t1/t2 = r2/r1 = p2/p1(root(m1/m2)
