What is the percentage by mass of iron (Fe) in the mineral hematite (F e2O3)? 69.9% to three significant figures. First find the total mass of the compound. 3 × 15.999 = 48 grams for Oxygen. 2 × 55.8 = 111.6 grams for Iron. adding these gives 159.6 grams per molecules F e2O3. Now divide the mass of Iron by the total mass for the compound.
