Why is the law of definite proportion important.?
In chemistry, the law of definite proportions, sometimes called Proust's Law, states that a chemical compound always contains exactly the same proportion of elements by mass. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition by mass. For example, oxygen makes up about 8/9 of the mass of any sample of pure water, while hydrogen makes up the remaining 1/9 of the mass. Along with the law of multiple proportions, the law of definite proportions forms the basis of stoichiometry.
What are definite proportions?
Definite proportions, also known as the law of definite proportions, states that a chemical compound always contains its component elements in fixed ratio by mass, regardless of the amount or source of the compound. For example, water (H₂O) is always composed of 2 hydrogen atoms and 1 oxygen atom, resulting in a consistent mass ratio of approximately 1:8. This principle is fundamental in chemistry, as it supports the idea that compounds have specific formulas and compositions.
Describes what elements are in a compound and in what proportions?
A compound is a substance composed of two or more elements chemically bonded in fixed proportions. The elements in a compound are present in set ratios determined by the compound's chemical formula. Each compound has a unique combination of elements and proportions that define its chemical properties.

Who said that a given compound always contains the same elements in the same proportions by mass?
This statement was made by French chemist Joseph Proust and is known as the Law of Definite Proportions. It states that a compound always contains the same elements in the same proportions by mass regardless of the source of the compound.

State the law of definite proportions?
The law of definite proportions states that a compound always contains the same elements in the same proportion by mass, regardless of the source of the compound. This means that for a given compound, the ratio of the masses of the elements is always constant.
