is always the same, regardless of the source of the compound?
Joseph Proust
Robert Boyle
Jacob Berzelius
John Dalton
- Joseph Proust: This French chemist formulated the Law of Definite Proportions in 1806. It states that a chemical compound always contains the same elements in exactly the same proportion by weight or mass, regardless of the sample's origin or how it was prepared.
- Robert Boyle: An English chemist and physicist, Boyle is best known for Boyle's Law, which describes the inversely proportional relationship between the pressure and volume of a gas.
- Jacob Berzelius: A Swedish chemist known for his work on atomic weights and his development of modern chemical symbols.
- John Dalton: An English chemist who is famous for proposing the atomic theory and Dalton's Law of Partial Pressures.
Joseph Proust's work on the Law of Definite Proportions made significant strides in analytical chemistry.
