The law of definite proportion was given by Joseph Proust in the Spanish city of Segovia in 1797. [2] This observation was first made by the English theologian and chemist Joseph Priestley, and Antoine Lavoisier, a French nobleman and chemist centered on the process of combustion. This is how Proust phrased the law in 1794. [3]

A few years previously, the French chemist Joseph Proust had proposed the law of definite proportions, which expressed that the elements combined to form compounds in certain well-defined proportions, rather than mixing in just any proportion; and Antoine Lavoisier proved the law of conservation of mass, which also assisted Dalton.

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.
