Dalton's law of constant proportion states that any sample of a chemical compound will have its constituent elements appearing in the same proportion by mass. Thus 8/9 of the mass of any sample of water will be oxygen and the remaining 1/9 will be hydrogen.
That is the law of constant composition.
The law of constant composition for compounds is a law in chemistry according to which any given compound always contains the same component elements in the same ratios, by mass. The ratios do not depend on where the compound comes from or the way in which it was produced.
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.
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.
The scientist who helped prepare the way for Dalton's work by developing the law of constant composition was Joseph Proust. Proust formulated this law, also known as the law of definite proportions, which states that a given compound always has the same elements in the same proportion by mass.
This was an idea of John Dalton.
No,Law of constant composition is valid only for compounds made from the specified isotopes of the element.
Answer: Apex ↓Ptotal = P1 + P2 + P3 + ...
The law of constant composition, proposed by Joseph Proust, states that a compound always has the same relative numbers and kinds of atoms regardless of its source or method of preparation. This law forms the basis of modern stoichiometry in chemistry.

The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.English chemist John Dalton
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.
