Q6)
Iron to be recovered from 25.0 g Fe2O3
Molar mass of Fe2O3 = (2*At. wt. of Fe + 3 * At. wt of O)
= 2(55.85) + 3(16)
= 111.7 + 48
= 159.7 g/mol
Iron present in one mole of Fe2O3 = 111.7 g
Iron to be recovered from 159.7 g Fe2O3 = 111.7 g
Iron to be recovered from 25.0 g Fe2O3 => (25.0 g * 111.7 g)/159.7 g
= 17.4859 g
Iron to be recovered from 25.0 g Fe2O3 = 17.5 g
