... Take, for example, the compound iron sulfide, FeS. The formula tells us that any amount of FeS contains equal numbers of Fe and S atoms. So suppose I have some iron and some sulfur and want to make 100 g of FeS. If I want equal numbers of Fe and S atoms, then I want equal numbers of moles of Fe and ...
