Law of Definite Proportions
The law of definite proportions states that a chemical compound always contains exactly the same proportion of elements by mass. The French chemist Joseph Proust conducted several experiments between 1798 and 1804 to make this discovery. At the time (before Dalton had proposed his atomic theory)...https://education.ti.com/en/activity/detail/law-of-definite-proportions
