What is Law of Definite Proportions in Chemistry? Learn with Kimavi in just one minute!

The Law of Definite Proportions states that a chemical compound always contains the same elements in the same proportions by mass.

This law is also known as the Constant Composition Law.

This law was developed by the French chemist Joseph Louis Proust in 1799.

An example of the Law of Definite Proportions is that water always contains 11.19% hydrogen and 88.81% oxygen by mass.

Another example is that carbon dioxide always contains 44.01% carbon and 55.99% oxygen by mass.

The Law of Definite Proportions is an important part of chemistry, allowing chemists to accurately determine the composition of a compound.

This law is also used to explain why matter is conserved during chemical reactions.
