Answer:

The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. ... For example, in a nitrogen dioxide (NO2) molecule, the ratio of the number of nitrogen and oxygen atoms is 1:2 but the mass ratio is 14:32 (or 7:16).

Answer:

Joseph Proust put forward law of proportion in 1779. This law was stated by Proust as “In a chemical substance the elements are always present in definite proportions by mass”.

For example- Carbon dioxide exists in nature in different forms and can be chemically produced in different ways. Yet, all the different samples of carbon dioxide will always contain the same elements. i.e. carbon and oxygen is in the same proportion by mass 3:8.
