Homework Help: Simple chemistry question! PLEASE?

  1. May 13, 2012 #1
    1. The problem statement, all variables and given/known data

    If you have 5 mL of Fe(NO3)3(aq) at a concentration of 0.200 mol/L

    How many moles of Fe ion do you have?

    3. The attempt at a solution

    Would it simply be (0.200) * (0.005) = answer


    or would you have to divide that answer by three since one Fe per three NO3?

    THANK YOU!

    There is only ONE Fe3+ ion for each Fe(NO3)3(aq). I think that answers your question.
