5.430g mixture of FeO and Fe3O4.

You react this mixture with excess oxygen to form 5.779g of Fe2O3. Can you help me calculate the percent by mass of FeO in the original mixture.

Find the number of moles of iron in (5.779g) iron(III) oxide which should be the number of moles of iron to start with in the iron(II) oxide. I think we're missing some information, like the mass of the original mixture?
