My professors teaches that M1= molarity of the stock solution (b4 dilution), V1= volume of stock solution, M2= molarity of solution after dilution, and V2= volume of diluted solution.. If this is the case, shouldn't the arrangement of your equation been different?.. For example, M1=0.500M (your stock solution). Based on the wording of the question, it sounds to me like 0.500M H2SO4 is the stock solution that is getting diluted..

@CBREEZE73 - in all honesty.....it does not matter which one you call m1 or m2....to be quite frank......but once you do decide what is M1....then make sure.....you pick its correct volume. Most people call M1andV1 for the original concentration and volume (which makes sense)...and M2andV2 is for your new stuff........But sometimes...you need to read and apply simple logic.....M2V2=M1V1 will give you the same answer as well as M1V1=M2V2.....:)......but i will see if I have goofed...just in case

@CBREEZE73 - you see how it says 100ml of 0.125M (in basic math we know these two numbers are connected they will be multiplied together) so we need to decide what are we going to call M1V1 and what we are going to call M2V2 does it really matter?Not really because in the end we will get the same answer. Here, I just called 100ml of 0.125M=M1V1-just because i seen them listed in the word problem first so i placed them in the equation (100)(0.125)=(0.500)V but (0.500)V=(100)(0.125) are equal.

@CBREEZE73 - does not our answers to this problem come out to the same values????

i bet this guy gets all the bitches.

you make my teacher look like an idiot.

really helpful.i've been studying the entire weekend and finally found something that helps :)

@joshuaqincoiancs Touche

[MrJazzyfication]

I wish u were my Chem teacher. So simple and to the point thank you very much kind sir for taking the time to help others.

[YooNique08]

why can't my teacher be like this :(

[joshuaqincoiancs]

@TheJordanwright IF NOTHINGS WRONG WITH OUR TEACHERS THEN WHY ARE YOU WATCHING THIS VIDEO, OBVIOUSLY YOUR TEACHER DIDNT TEACH CORRECTLY

[Itshardtopronuncius]

thanks alot!

[TheJordanwright]

nothing is wrong with our teachers, we just need to listen guys :) any-ways thank you so much this helped a whole bunch for assignment.

I wanted help Tomorrow I got My Final Exams Up and We got Chemistry and We got This and The GAW laws As in Charles Law and So on Since they are ALL similar Formulas Like Boyles P1V1=P2V2 Like this and V1/T1 Stuff like that : MY POINT IS

The Teacher Said They are All Multiple Choice so I wanted to know How do we Know what are we Solving for? Are we Solving for M/V, P/T, V/T P/V or P/V/T..! Any Help Sir?
