Question: An iron ore sample contains Fe 2 O 3 plus other impurities. A 752- g sample of impure iron ore is heated with excess carbon,

An iron ore sample contains Fe₂O₃ plus other impurities. A 752- g sample of impure iron ore is heated with excess carbon, producing 453 g of pure iron by the following reaction:

Fe₂O₃(s) + 3C(s) → 2Fe(s) + 3CO(g)

What is the mass percent of Fe₂O₃ in the impure iron ore sample? Assume that Fe₂O₃is the only source of iron and that the reaction is 100% efficient.
