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.
