Question

explain the law of Definite proportion with an example​

Answer 1

law of definite proportion

A pure chemical compound prepared by any method consists of the same elements combined together in a fixed proportion by mass

Joseph Proust noticed that all the compounds of two or more elements and each such compound had the same elements in the same proportions, irrespective of the preparation methods.

example.

water obtained from the different sources consists of the same two elements hydrogen and oxygen, in the ratio 1:8 by mass.

similarly the mode of preparation of the compounds may differ but the composition will never change. it will be in the fixed ratio.

Answer 2
