Hematite (Fe2O3) and magnetite (Fe3O4) are two ores used ...In hematite... The two ores of iron are hematite and magnetite with the chemical formula Fe2O3 and Fe3O4 respectively. To determine which of the compounds has a higher percentage of iron per kilogram first the molar mass of the two compounds has to be determined. Iron has a molar mass of g/mole and oxygen has a molar mass of 16 g/mole.
