The Law of Definite Proportions. Joseph Proust (1754-1826) formulated the law of definite proportions (also called the Law of Constant Composition or Proust's Law).This law states that if a compound is broken down into its constituent elements, the masses of the constituents will always have the same proportions, regardless of the quantity or source of the original substance.

Proust's Law of Definite Proportions. Proust's Law of Definite Proportions was created by Joseph Proust (a French chemist) in 1794 after realizing during his experiments that copper (II) carbonate is always in a fixed mass ratio of 5.3:1:4 (copper:carbon:oxygen) . Originally scientists believed that compounds could be composed of different mass ratios of elements and still be the same compound.
