Mass Percent of a Solution Made Easy: How to Calculate Mass % or Make a Specific Concentration
This is a whiteboard animation tutorial on how to solve Mass Percent calculations for solutions.

The Mass Percent of a solution is equal to the grams of solute per 100 grams of solution. The formula is:
Mass Percent = ((mass of solute) / (mass of solution)) x 100%
This equation may be rearranged to solve for any one of those three variables. The mass may be in any mass units as long as the mass units are consistent with each other. It is also useful to realize that the density of water is approximately 1 g/mL, so volumes of water in mL are equal to masses in grams.
In this video, I also describe how to make a solution of a certain mass percent.

I love your videos; they are so easy to follow! Could you possibly make one explaining how to find Molecular geometry? That would be a blessing!
I learned more from this video than my professor so you get my like and subs

yeah ur right my teacher just showed me a bunch of numbers on a paper without a label
Thank you for such a thorough explanation. You rule, Sir! 🤟🏽
Thanks, you really explain it in detail!
Glad to see a new video!

Oh my God You made far more simpler! than my school! thanks
Can you compute mass of the solute given the mass of the solvent and mass percentage?
Your Videos are so amazing I'm greatful for You, I learned a lot and knew things that I didn't know Move on and teach us more, we all suppot you Thank you so much

Thanks!
Teacher thanks for all I've been struggle to the lesson because it's hard T~T now I get it. :D
Thanks you made it easy for me😃
Bro define how to calculate kc value
Thankz very much.,😊😊God bless.
It feels like its sticking in!! i'm actually memorizing it as u go by!!
Thank you😊
Thank you
This is great.
I red several times in my text book but I can't understand properly.Every videos of yours make me confident about those topics.After watching your videos if I open my book that makes me think it's unnecessary to learn from book.
I easily learned
Can u please make more vids about percent by mass that would be awsome 😊 cause i cant qutie understand it 😅 thank you😀👍
You've saved my life

why you have used mass of solution=mass of solvent+ mass of solute in example 2 alone and not in example 1... can u explain...

been an year since op posted but still, in example 1 we were given the volume of the whole solution while in example 2 we were given volume for the solute and the solvent. A solute and a solvent combine to make a solution which is what is asked of us in the formula. That's why we add the solute and solvent in the second example and not in the first :))
why in one problem u used the mass of solution as given in question 1 and in question 2 u added mass of solute nd solvent

Ketzbook ummm I have a question and I hope it will be answerd (sorry for killing the Thankful mood of this comment section but like most of the others here this vid really and TOTALLY helped me too so I'm thankful like them too), ok so in calculating the mass of a solute what formula or what should you do to get the mass of the solute if the mas of the solution wasn't given? Please pleeeeeeeeeeeeeaaaaaaaaase answer I'm having a totally hard time understanding my teachers solution so Pleaaaaaaaaaaase tell me what to do when the mass of the solute isn't given. This is the problem that is quite similar to the one I need to solve just so you know what I mean A solution is prepared by dissolving a certain amount of solute in 500 g of water. The percentage by mass of a solute in a solution is 2.38. Calculate the mass of solute

I thought I did one like this. x = mass of solute x / (500 + x) = 0.0238

Jesus ……Americans better don’t teach maths please!
So easy but Americans make it complex……you need Asian as maths teacher if you want to improve your maths teaching level……you suffer and confuse American students
