Suppose that an endpoint is reacted when 30 moles of KMnO4 was added. How many moles of Fe^2+ was there originally.
I thought the answer was 150 moles.

Oxidation is the loss of electrons. So Fe goes from +2 on the left to +3 on the right and Mn goes from +7 on the left to +2 on the right. Which loses electrons. You try writing the equations.
If you have 30 mols KMnO4 you must have reacted it with 30 x 10/2 = ? and that sure looks like 150 to me.
