A compound containing 7.9 g of iron (Fe) has a total mass of 73 g. Assuming that one mole of the molecule contains one mole of iron, what is the molecular weight (in g/mol) of the compound?
Strategy
The mole ratio between the compound and Fe is 1:1, therefore, we can assume the general formula: FeX (X is unknown). The mass of FeX is 73 g and it contains 7.9 of Fe.
