A sample weighing 3.106 g is a mixture of Fe,0, (molar mass=159.69 g/mol) and A1,0, (molar mass 101.96 g/mol). When heat and a stream of H, gas is applied to the sample, the Fe, O, reacts to form metallic Fe and H,O(g). The AI,O, does not react. If the sample residue (the solid species remaining after the reaction) weighs 2.715 g, what is the mass fraction of Fe, 0, in the original sample? mass fraction: Fe,0, g original sample ENG 00 11:56 AM 6/7/2022
