Question

Which part of the Dalton&#x2019;s atomic theory came from the law of constant proportions given by Proust?

Philoid · Accepted Answer

According to law of constant proportions describes that, “a chemical compound always contains same elements in definite proportion by mass and it does not depend on the source of compound.”

This law gives result to the postulate of Dalton’s atomic theory which states that, “When two elements combine to form two or more than two different compounds then the different masses of one element B which combine with fixed mass of the other element bear a simple ratio to one another.”
