thanks so much for your kind comment! i'm very busy and can't promise that i'll make videos on certain topics, but i always consider requests when i'm deciding what topics to address. so please let me know what might be helpful for you to see.
Hey Tyler, I created an account just to tell you this. I have been reading about mole (your other video) and molarity and molality for more than 20 years (I am a physician). I never had it explained this easy. You are awesome!!
Tyler, I want to thank you in name of all my students for your great videos. Our school, like most high schools, had to go to distance learning during this corona virus pandemic. While preparing my lessons I was so happy I could depend on your videos for excellent instruction. You always explain concepts so well and detailed that I feel my students will have an excellent foundation for their future chemistry classes .

Been subscribed to you for so long now, I've stopped since my A-levels but I'm preparing for a prelim test and I'm recapping. Thank you so much for the videos you've posted. You've got a knack for teaching!
Yes, you're absolutely right. But usually that difference is so small that it doesn't matter, even in solvents of different densities. The one situation where it does really start to matter is in solutions that have a very high concentration of solute, so if you're dissolving a whole ton of something into a solvent, then that can really start to add up.
Tyler, thank you so much for your channel. I am a mature student that is trying to upgrade his high school credits online, through community college. If it wasn't for you doing this channel, I would NEVER have been successful, I owe you a great deal of thanks.
This guy....is saving my life...this and the gas laws and all that...helping me for passing the exams...Thanks a lot! :) But which is greater...Molaltiy or Molarity?
You are my Chem savior! My college professor's explanation was not even close to yours. You should host lectures where you teach professors HOW to teach these topics.
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
one more thing, the reason some chemical equation preferred molal over molarity is that molality wont be effected by the temperature. the heat that is generated towards the solution will make it's molecules expanding therefore the volume increased, but the mass remains the same
Your a wonderful instructor, professors should watch your videos and learn from you so they can teach better. Thanks for breaking it down and making it simply =)
even ur eleven year old vid is better than my teacher explaining 3hrs for this simple topic in this era of digital board and facility (i wish ur were born in india )
Thank you so much for explaining the significance and differences between molality and molarity. Very often do instructors tell you to simply "plug the numbers into the formula". However, it is so much better to have access to a more thorough explanation.
Hi, i just wanted to say that i seriously love your videos and i was worried that you had stopped making them because i hadn't seen any videos pop up in my homepage for ages! I am in a vital year at school this year and you made this video just in time! please reply to my message so i know you have actually read it because i have a few requests if it were possible for you to do.
OMG, Seriously THANK YOU!!!! I kept telling everyone that wouldn't the total amount of solute and solvent change btwn Molarity and Molality... everyone kept looking at me cross-eyed, that is until I found your video!!! THANK YOU
Damn you scientists for SUCKING at naming things. My turn: Moles Solute / Liters of Solution = MoLiSol. MolaLi. MolaLity. MolSolurity Moles Solute / Kilograms of Solvent = MolGraSol. MolaKi. MoGrarity. MolSolvency. My names have CLEAR OBVIOUS differences to avoid any confusion, and are related to what they mean.
Thank you so much for replying I understand you may be very busy but these are just a few requests if it were possible for you to do a couple or even one - solutions; suspensions; colloids - saturated, unsaturated and supersaturated solutions - Henry's law - Enthalpies of solution This is where we have studied up to and I know that there are many videos out there on these topics but i fail to understand them or my school teacher as much as i understand you! Thanks again for taking time to reply
When people say a solution is less or more concentrated, they actually mean that the moles(atoms/molecules) of the solute are less or more crowded together in a solution? Shouldn't that say that the concentration is actually the concentration of a solute (in a solution )? I think about certain details so I'm sorry if it sounds weird.
Bro, I liked your work. I was unable to understand this concept but after watching your video its simple for me now. Thanks a lot and by the way I am From INDIA :)
our a wonderful instructor, professors should watch your videos and learn from you so they can teach better. Thanks for your wonderful videos....But why you didn't come up with videos recently. We like to see you soon on TH-cam....Thanks a lot Sir...
I have a funny question, is it molar and molal concentration of solute or solution? You mention a molar of solution but isn't it molar concentration of solute in a solution (or simply molar concentration of solute)? I know it's just the naming but it still confuses me a bit, I would say molar concentration of solute in a solution and molal concentration of solute per solvent?
Something which can be explained so easily with the help of examples, is made so much difficult by my stupid teacher....Thank you! Your videos are life saver
So if I'm interpreting this right, there should also be another very slight (in this example at least) difference, but still important. In a 1M sol'n there is 1L of CaCl2 + Water, which would weight out to basically 1kg. However in the Molality it will actually be 1.111kg, which is 1kg of Water + 111.0g of CaCl2. Is this correct?? This would no doubt become a more significant difference also in different density solvents.
I'm sorry I forgot to say this, so the correct term would be the molar or molal concentration of the solute (in a solution), right? And one more thing, so we just assume the entire amount of solute is dissolved, right? Like there isn't any part of it that is not dissolved, since the definition of concentration is the amount of solute dissolved in a solution. I hope you can answer my questions, thank you.
No, because the formula for molality is MOLES divided by kg of solvent. You would get 111 molal if you divided GRAMS by kg of solvent, but you want to use moles, not grams. As you'll see in the middle of the screen at 3:27, 1 mole of CaCl2 weighs 111 grams, so you have 1 MOLE.
or what your gunna try to correct me?...get outa here tyler doesnt need haters like you....and as for my language read between the lines ------bitch-----

Normality?
Can you please do a video on normality
Mole Fraction
Please take your job as a tutor in our school in India....
Precisely Tamilnadu.....
TH-cam: NEVER TAKE DOWN THIS VERY CLEAR & IMPORTANT VIDEO!
i think my teacher needs to watch this video
Lol...
I m your teacher !😑
U right
😂 even my teacher
Actually my teacher watches taylor’s videos

Tyler, you are the best Chemistry teacher! I'm doing well in my Chemistry class thanks to your videos.
3:48 - 3:49 That's what I was thinking in chemistry class, and that is why I have to watch this video.
HAHA
but then what's morality !???

Molality does not change with temperature but molarity does
Shouldn't it depend on the density of solution and solvent?
@@srirampatnaik9164 no it depends on volume

hey u in 11th grade?
Excellent!, Chef Kiss🤌. Thank you

I FUCKING LOVE THIS GUY
You explain this so well, but what’s also nice is your voice is clear and easy to follow. For English speaking people, that is.😁
can you please make a video about Normality?
I asked him the same in other video :D so 2 votes !
Yes yes an English video about normality pleeeeeese!
being normal is incredibly overrated tho.
your lectures are conceptual & easy to understand.
Best until today 🤗
Exceptional explanation. It made things very clear.
Your video helped me so much
you're really good instructor and professor 👍🏻
Sir you are the best teacher.👍
That was so easy and understandable tysm 🍮
your videos helped me so much to understand chemistry
Idk why u are not making more videos.. But u are amazing.
Been encountering this lesson in junior high, in senior high. I'm now in college and here i am again lol
same, got my uni entrance exam tomorrow 😹 learned this in 10th grade
Hi, i just wanted to say that i seriously love your videos and i was worried that you had stopped making them because i hadn't seen any videos pop up in my homepage for ages!

Crystal clear explanation... Go for it guys if u wanna clear your concepts
The Chemistry God puts out another great video.
OMG, Seriously THANK YOU!!!! I kept telling everyone that wouldn't the total amount of solute and solvent change btwn Molarity and Molality... everyone kept looking at me cross-eyed, that is until I found your video!!! THANK YOU
I really love the way you teach!!❤❤❤
Damn you scientists for SUCKING at naming things.
My turn:
Moles Solute / Liters of Solution = MoLiSol. MolaLi. MolaLity. MolSolurity
Moles Solute / Kilograms of Solvent = MolGraSol. MolaKi. MoGrarity. MolSolvency.
My names have CLEAR OBVIOUS differences to avoid any confusion, and are related to what they mean.
Lmao 💀💀💀
Please make a video on Normality, Equivalent Weight and n factor. Thank you for the interesting videos that you make.
ur teaching is very easy to understand! LIKE!
The most underrated channel
from 2020 and still love this video
Thank god, your a blessing man I was struggling on my ap chem work and because of you it’s easy
Thank you so much for replying I understand you may be very busy but these are just a few requests if it were possible for you to do a couple or even one

Please make a video about Normality and Formality
world need more people like you
Really good and very helpful .. I was able to clear my doubts
Thank you for helping me with my future homework! You really know how to explain the concepts. 💯
Thank You..It was simply awesome.Do upload more videos of this kind
God bless you sir.

Only good teacher can teach like this
There are just three more concepts that I would like for him to touch on. Thats is this: Normality, osmolarity, and osmolality
This man is so much better than my teacher, who is being paid a salary. This guy works off of add revenue
Bro, I liked your work.
I was unable to understand this concept but after watching your video its simple for me now.
Thanks a lot and by the way I am From INDIA :)

HI! I know I'm late and this vid was 6 years ago but I do hope you can make a video about Molality Sample Exercises. Thank you :)
He has already made a molality practice problem video. I hope it isn't too late to be of use to you ☺☺☺.
يا شيخخخ احوب خااالتك 😘😘😘💖
Boss/Sir/ you own my heart and I can't seem to understand how to thank you. You exactly explained how I wanted to ❤️
Thank you
Do you think you could make a video on molality practice problems?
i seriously love your videos
Simply awesome. Just mind blowing. Thank you!
NOW I GET IT THANK GOODNESS
Tyler, you are the man. awesome explanation. ty.
ياخي اشكر ام الي خلفتك
you helped me a lot man
do you have some videos on structure of solids and its numericals?
Thank u so much . Hope my teachers c this and learn from u
Excellent explanation. Keep it up!
Best explanation 😊
that one hot chemistry teacher
bruh
That student who is only here for the bod. I mean seriously?
I'll definitely want my teacher to see your videos. This is how science is taught. Not like how my teacher does. 😋
3:27
Shouldn't it be 111 molal CaCl2?
Correct me if I'm wrong
No, because the formula for molality is MOLES divided by kg of solvent. You would get 111 molal if you divided GRAMS by kg of solvent, but you want to use moles, not grams. As you'll see in the middle of the screen at 3:27, 1 mole of CaCl2 weighs 111 grams, so you have 1 MOLE.
Tyler DeWitt Awh I guess I got it. Thanks alot :) (y)
amun6416 I haven't corrected him, I've asked him a doubt. Also, please mind your language.
or what your gunna try to correct me?...get outa here tyler doesnt need haters like you....and as for my language read between the lines ------bitch-----
amun6416 Well, it just makes you appear indecent.
amun6416 bahahaha
Do you also need to add solute to the 3rd flask then a solvent again until it reaches 1 liter or just add solvent up to 1liter???
This video saved my life
OMG!! Thanks a lot Tyler. U made it easy. U r amazing 😍
hey can you add video of solving molality i learned a lot from the the molarity practice videos thx a lot
but can you make a video on solution and suspension
thankyou so much for all your videos! you're amazing.
Keep going
so is Molality ALWAYS greater than molarity in aqueous solutions, or are there factors such as density that will change that ?
You my friend. You. You have saved me from a date worse than death, and you will be rewarded in the afterlife. Peace be with you
