An iron ore was analyzed by dissolving a 2.9912-g sample in concentrated HCI. The resulting solution was diluted with water, and the iron(II) was precipitated as the hydrous oxide Fe203-XH20 by the addition of NH3. After filtration and washing, the residue was ignited at a high temperature to give 0.8394 g of pure Fe203 (159.69 g/mol). What is the %Fe3O4 in the iron ore sample? A 6.97% B) 13.94% 20.90% D) 27.87%
