Question

State law of definite proportion.

Answer 1

• French chemist Joseph Proust proposed the law of definite composition or proportions based on his experiments.
• The law of definite proportions, also known as the law of constant proportions, states ‘that the individual elements that constitute a chemical compound are always present in a fixed ratio’ (in terms of their mass). This ratio does not depend on the source of the chemical compound or the method through which it was prepared."
