To determine the charge of the iron, you must know the charge from the oxygen. An oxygen ion has a -2 charge. Therefore, 3 oxygen ions have -6 charge. We know that charges must cancel out. If it were Fe+2 in the compound, the overall charge would be -2, which isn’t correct. So, we can conclude that it is Fe+3 found in iron (III) oxide.
