Working out stock solutions

  1. Apr 28, 2013 #1
    1. The problem statement, all variables and given/known data
    I need to make a stock solution of 1g/L. The compound is called resveratrol with a molecular weight of 228.24g/mol. I need the final volume to be 100mL. How do I find the volume of this compound needed to make 1g/L?. I know that the amount of moles is equal to the amount of compound there is divided by the molecular weight. And I'm sure I have enough resveratrol to make 1g/L.

    Or would I just say that 0.1grams of resveratrol needs to be added to 100mL?

    Yes, that's perfectly enough.
