Mr.Millings! I had you my junior year five years ago, now I’m in my final year of collage before nursing school studying for my midterm and I found your video! Thanks for everything and help, you’re one of the reasons I’m at where I am in my life.
mass percent = mass of solute ---------------------- Mass of solute + mass of solvent ×100% add first the mass og solute + mass of solvent divide the mass of solvent and mass of solute and multiply it to 100%
what if you don't have the grams of the solution? I have s dilution problem that says "What is the final concentration of a solution obtained by mixing 150. ml of solvent with 250. mL of a 15.5 % w/w ethanol solution?"
I got this part but unable to know when are to different solutions exp. Determinate mass percent of NaCl in solution containing 12.5 g NaCl, 20.5 g of glucose and 150 mL of water?
Does anyone know how to calculate this please? A solution is made by mixing 240ml 30% KBr solution and 150ml 12% KBr solution. Calculate the mass percent of KBr in the solution. ...the ml are confusing me :(
You first divide 25.5 by 175.5 and that should give you 0.1452991... and then you take that number and multiply it by 100 and that should give you 14.5% because the decimal in the first answer moves two decimal places to the right after you multiply by 100.
@@gamerrenzjan6491 or you can make 17.5 and 25.5 into fraction 175/10 35/2 (lowest term of 175/10 is to ÷ by 5) 255/10 51/2 ( is da lowest term of 255/10 also ÷ by 5) 51/2

That is so cool! Keep up the good work. Hopefully my channel will help you out. If you need any help let me know.
Did you become a nurse?
Explained it way better than my professor. Thank you!
Thank you this lesson was hard for me to understand but thanks to you I finally get it
THANK YOU SO MUCHHHH!!!! I was also thinking the same thing. This deserves more reviews.
Answer all my questions in one video !!! Thank you !
My Favorite Subject "SCIENCE" Has Collided With The Nigjtmare"MATH"!!!
Thank you for saving me from my suffering 😂
Thanks the lesson you gave us is easy then I thought it would 😊
I been watching all your videos after my chemistry lectures and currently studying for my finals thanks for all these videos
Best of luck!
@@ChemAcademy hes still replying to comments after 7 years what a legend

I couldn't understand it, but now it is clear for me. Thanks ☺️
THANK YOU SO SO MUCH YOUR A LIFE SAVER!!!!!
Thank you so much sir. Very clear explanation
Shout out to the all the Rogers students, learning from da videos
+DVHFTW
Honestly, I don't get why the hell we multiply by 100%. It is the exact same thing as multiplying by 1.
thank you so much really helpful ..... wish me luck
mass percent = mass of solute
----------------------
Mass of solute + mass of solvent ×100%
add first the mass og solute + mass of solvent
divide the mass of solvent and mass of solute
and multiply it to 100%

Raphael Carlos Dyangco thank you so much
It was helpful thank you
Understood everything. Ty sir😁
Thank you so much !!!!!
MODULES BROUGHT ME HERE.
Me tooo
This was so helpful, thank you!
Nice men
Wow that's too simple
Thank you sharing this lissan 😌😌
Thanks you for you so much

Great Video. You deserve more views
+Enzo Vinholi Thank you....spread the word.
Thank you sir👍😊
Thanks so muh sir
THANK YOUUUUU
Hi, is this video formulas same as w/w, w/v, and v/v ?
thank you ive mastered this lesson. too bad i wont use it in my everyday life lol
I got this part but unable to know when are to different solutions exp. Determinate mass percent of NaCl in solution containing 12.5 g NaCl, 20.5 g of glucose and 150 mL of water?
Determinate?
Did you rounded off the first problem?
Tyyy
Hi.. What if the solute is in pounds while the solvent is in gallons, do I have to convert both into grams?
(I'm stupid so pls confirm this for me😶)
Does anyone know how to calculate this please?
A solution is made by mixing 240ml 30% KBr solution and 150ml 12% KBr solution. Calculate the mass percent of KBr in the solution.
...the ml are confusing me :(
so easy
HHAHAHAHA STOP LAUGH! HHHAHAHAHAHHAHA STOP!
How is that even 14.5!? Is it add divide subtract or multiply
You first divide 25.5 by 175.5 and that should give you 0.1452991... and then you take that number and multiply it by 100 and that should give you 14.5% because the decimal in the first answer moves two decimal places to the right after you multiply by 100.
Yeah science lab mcpe
@@gamerrenzjan6491 or you can make 17.5 and 25.5 into fraction
175/10
35/2 (lowest term of 175/10 is to ÷ by 5)
255/10
51/2 ( is da lowest term of 255/10 also ÷ by 5)
51/2
arigatu
How did get the 13 mass percent?
sorry sir but your second ex answer is uncorrect
the answer is 7.8 g
Did you try rounding it off because I got 7.9 when I did
He made it so complicated
A saturated solution weighing 30g. gave 5g. Of solute its mass percentage is what?
Please send the answer with calculations
3:28
It's 13.04 on my calculator
SAME!
i hit like at minute # 3
I really don't get example #2
Despite everything it ends up with 0.07875
Nice but say in terms of density and upload moooore videos
RCHV?
7 year's agoo....
I have a given, how did I got the answer? Idk it’s in my book lmao, imma a freshman :3 lmao
Mass of Solute=20
Mass of Solution=600 x 100% =3,23%
Face palm, thanks.

Huh? What’s wrong?
For me this is useless. Couldn't understand anything.
You're useless
