Asample weighing 3183 g is a mixture of fe2o3 molar mass , Ask an Expert

Academics

A sample weighing 3.183 g is a mixture of Fe2O3 (molar mass = 159.69) and Al2O3 (molar mass = 101.96). When heat and a stream of H2 gas is applied to the sample, the Fe2O3 reacts to form metallic Fe and H2O(g). The Al2O3 does not react. If the sample residue weighs 2.453 g, what is the mass fraction of Fe2O3 in the original sample? ________ g Fe2O3/(g original sample)
