This law has also named the law of definite proportions and like Proust’s law and it states that the compounds are made up of different elements and the elements are present in it in a fixed ratio. This means that any sample of a compound consists of the same elements in exactly the same proportions.
In the case of non-stoichiometric compounds, the proportion of the elements changes, hence they do not obey this law. Moreover, the polymers that exist naturally also disobey this law.
Example of Law of Constant Composition:
Consider an example of pure water which is composed of hydrogen and oxygen in a fixed ratio i.e., 0.11g of hydrogen and 0.88g of oxygen. This ratio remains the same no matter what the source of water is.
