What formula do I use to calculate the mass of KCl that is required to make 625 mL of a 0.200 M solution?

See the other KCl problem to which I responded.

DrBob I tried the formula you gave me and Im still not coming up with the correct answer. The answer has to be in grams and it isnt coming out correct. The answer is 9.3 g and the formula isnt giving me that answer or Im not doing it right. Help please.
