Question

explain the law of Definite proportion with an example​

Answer 1

Examples of the Law of Definite Proportions. Let us take, for example, the compound, water. Whatever the source of water, its composition is that of two atoms of hydrogen and one atom of oxygen. ... This translates into a ratio of 1:8 of hydrogen to oxygen in water

Answer 2

In chemistry, the law of definite proportion, sometimes called Proust's law or the law of definite composition, 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. For example oxygen makes up about 8/9 of the mass of any sample of pure water, while hydrogenmakes up the remaining 1/9 of the mass. Along with the law of multiple proportions, the law of definite proportions forms the basis of stoichiometry....
