Reaction of FeSO4 and KMnO4

An impure 0.500 gram sample of FeSO4 reacts with 20.0 ml of 0.0200 M KMnO4
Assuming that the impurities do not react with KMnO4 what is the percentage of FeSO4?

The equation given is MnO4- +8H +5Fe+2 -------->Mn2 +5F3+ + 4H2O
so far I got:
.0200l *.0200M MnO4- =4*10-4 Moles of MnO4

How do I get to the moles of Fe?
