Yo guys.
I know that It might be super easy and I am just fucking stupid... But I never have been good with chemistry calculations, or any math related stuff...
Can somebody explain to me how the answer is "C". I have an exam on Monday, and I am panicking, and this is only one of the first calculations.

Why so lazy? Check the text, lecture notes, past exams, past homework, google. Ask your friends and TA.

What? Did I write anything wrong? Here's more, skip the problem for now, do other ones. No one in the right mind asks /sci/ for academic help.

You want to know the final concentration of EDTA in units M which is mol/L. So you take the amount of mol of EDTA (which you find by .744/372.24) and divide it by the total volume of the final liquid (20 mL).

Divide by total volume of 0.02 L.

Units, units, units.

I'm gonna be honest with you. If you are in university and you can't do this problem in your head or at least with a calculator or wolfram alpha at hand you will not make it. Better drop out right now and become a carpet cleaner or something.
If you are in high-school, then you should fuck off you underage faggot.
