Law of multiple proportions

chemical law that, if two elements form more than one compound, then the ratios of the masses of the second element which combine with a fixed mass of the first element will always be ratios of small whole numbers

The law of multiple proportions states that when two chemical elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.[1] It was first described by John Dalton.[2]
