4. An iron ore was analyzed by dissolving a 1.1324-g sample in c-HCL. The resulting solution was diluted with water, and the iron(III) was precipitated as the hydrous oxide Fe₂O, - xH₂O by the addition of NH3. After filtration and washing, the residue was ignited at a high temp. to give 0.5394 g of pure Fe:O) (159.69 g/mol). Calculate: (a) the % Fe (55.847 g/mol) and 2 Fe (b) the % Fe O. (231.54 g/mol) in the sample. Fe₂O3 11 3 Fe (33.32%) Fe 0,
