Joseph Proust, based on experiments conducted at the end of the 18th Century claimed that elements combined in constant proportions. Dalton's atomic theory, (1903) built on this earlier work and put it into a theoretic framework.

Does compound follow the law of constant composition?
because 789
Atoms of different elements combine in whole number what?
That is the law of constant composition.
What in an expression of Dalton's law constant?
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.
What is meant by the law of constant composition for compounds?
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.
Why is the law of constant composition important to chemistry?
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.
Who stated the law of constant composition?
Joseph Louis Proust (1754-1826), In 1799 Proust stated that "Compounds always contain the same elements in a constant proportion by mass." This statement is now called law of definite composition or the law of constant proportion.
If Law of constant composition true for all types of compounds?
No,Law of constant composition is valid only for compounds made from the specified isotopes of the element.
Who put forward the law of constant proportion?
This was an idea of John Dalton.
What is an expression of Dalton's law constant?

Evidence that supports the law of constant composition?
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.
Who wrote the law of definite proportions and Law of multiple proportions?
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
