The law of multiple proportions states that when two elements form more than one compound, the masses of one element that combine with a fixed mass of the other element are in ratios of small whole numbers. CO (carbon monoxide) and CO2 (carbon dioxide) are examples where carbon combines with oxygen in different ratios, illustrating this law.
