Final answer:
There is 1 mole of Fe in 1 mole of FeO, which suggests a 1:1 ratio. For Fe2O3, there are 2 moles of Fe for every mole of Fe2O3.
Step-by-step explanation:
The student has asked how many moles of Fe are in 1 mole of iron oxide FeO. However, there is a discrepancy in the question. The empirical formula of FeO suggests a 1:1 mole ratio of iron to oxygen. This means there would be 1 mole of Fe for every mole of FeO. Yet, if the student meant iron (III) oxide, whose empirical formula is Fe2O3, there would be 2 moles of Fe for every 1 mole of Fe2O3 because the formula unit contains two iron atoms.
