Question

state the law of constant proportion. give example​

Answer 1

Answer:

The law of constant proportion was given by Joseph Louis proust. It says that in a chemical substance (compound) elements are always present in definite proportion by mass. For example: In a compound such as water the ratio of mass of hydrogen to the mass of oxygen is always 1:8.

Answer 2

Explanation:

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, pure water will always contain hydrogen and oxygen in a fixed mass ratio (a gram of water consists of approximately 0.11 grams of hydrogen and 0.88 grams of oxygen, the ratio is 1:8).
