WebSep 23, 2024 · 18.12g Fe_2O_3 Regardless of the other reactant quantities necessary, and the final products, the conservation of mass requires that we have 12.8g of Fe in the iron oxide if we expect to get at least 12.8 g of Fe metal product. SO, the question is, "What mass of Fe_2O_3 contains 12.8g Fe?" By molar ratio, we have 2 moles of Fe per mole of Fe_2O_3.
