To prepare a 400 mL solution of .7500 M NaC2H3O2, how many grams of NaC2H3O2 would be needed?
I am wondering if I set this up, I got an answer of .0435 g NaC2H3O2. But i'm not sure if that is right? Is that the correct answer?
That isn't the answer I obtained.
How many moles will you need? That will be M x L = 0.7500M x 0.400L = 0.300 moles. How many grams is that?
grams = moles x molar mass NaC2H3O2 = ??
