WebJun 19, 2015 · The law of definite proportions states that a compound always contains exactly the same proportion of elements by mass. This means that the composition of a … In chemistry, the law of definite proportions, sometimes called Proust's law or the law of constant composition, states that a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation. For example, oxygen makes up about /9 of the mass of any sample of pure water, while hydrogen makes up the remaining /9 of the mass: the mass of two elements in a compound are always in the same ratio…
