Law of Constant Proportion

The Law of Constant Proportion, also known as the Law of Definite Proportions, is a fundamental concept in chemistry. It states that a chemical compound always contains the same elements in the same proportion by mass.

This law implies that the ratio of the masses of the elements present in a compound remains constant, regardless of the amount of the compound or its source. It helps to establish the identity and purity of chemical substances.

Example sentences:

1. The law of constant proportion states that water always consists of two hydrogen atoms and one oxygen atom, regardless of its source.
2. According to the law of constant proportion, carbon dioxide will always contain one carbon atom and two oxygen atoms per molecule.
3. The discovery and understanding of the law of constant proportion greatly contributed to the development of modern chemistry.
