2 questions, I'm Having trouble figuring out how to calculate the moles of a solute in a solution based on the molarity and the volume. Here is what I'm working with.

1) "Use molarity of the stock solution of aspirin/Fe(No3)3(aq) (0.0044mol) and the total volume of the stock solution (500 ml) to calculate number of moles of ASA in the pill (used as the solute.) The pill weighed .379g."

"Convert the Moles to grams and calculate the %ASA in the pill."

Any ideas?

    I don't understand the "data" part of the question but mols = M x L
