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!
