That is the law of constant composition.
It means that in any pure compound, the proportion of constituent elements (by mass) is a constant. This allows their chemical formulae to be determined.
The law of constant proportion states that a pure chemical compound always contains exactly the same proportion of elements by mass.This information, together with the atomic masses of the elements in the compound enable scientists to determine the formula of a compound.
No,Law of constant composition is valid only for compounds made from the specified isotopes of the element.

The law of constant composition applies to chemical compounds, stating that a compound is always made up of the same elements in the same proportion by mass. This means that the ratio of elements in a compound is fixed and does not change regardless of the source or method of preparation.
One drawback of the law of constant composition is that it may not hold true for all substances, especially those with variable composition such as alloys or solid solutions. Additionally, it assumes that compounds are made up of discrete units, which may not always be the case at the molecular level. Finally, the law does not account for isotopic variations in elements.
This law is not valid for all chemical compounds (ex. nonstoichiometric compounds).
Joseph Proust, a French chemist, is credited with stating the law of constant composition, which states that a given chemical compound is always composed of the same elements in the same proportions by mass.

That is the law of constant composition.
The chemical composition of nonstoichiometric compounds do not respect the law of definite proportions.
Yes, a mixture does not obey the law of definite composition. Mixtures can have varying proportions of different substances, whereas compounds, which obey the law of definite composition, have a fixed ratio of elements.
A piece of evidence that is commonly used to prove the law of constant composition is that any sample of water is 88. 71 percent oxygen and 11. 19 percent hydrogen. It was formulated by Joseph Proust.
The law of definite proportions states that a compound always contains the same elements in the same proportion by mass, regardless of the source of the compound. This means that for a given compound, the ratio of the masses of the elements is always constant.
