Calculate the % Fe304 (231.54 g/mol) trom an impure ore that is 2.146 grams. The ore was dissolved in concentrated HCl and all the iron

Calculate the % Fe304 (231.54 g/mol) trom an impure ore that is 2.146 grams. The ore was dissolved in concentrated HCl and all the iron was oxidized to Fe" after addition of HNO3. This was diluted with water and formed Fe(OH)3 (106.87 g/mol) with the addition of NH3. The filtrate was ignited anda pure Fe203 (159.69 g/mol) with a weight of 0.451 was obtained. Y* 2/159.69x 231.54/3 *1/x
