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(IlI) 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). If the sample came from an extracted ore that is 50 kg in total, how much iron can be extracted from it? A 9.815 g Fe B 9.815 kg Fe 13.94 g Fe 13.94 kg Fe
