“A sample of a pure substance always consists of the same elements combined in the same proportion by mass.” Which law has proposed this? Explain the law in details.
In chemistry, the law of definite proportions, sometimes called Proust's law, or 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
