John Dalton gave the law of multiple proportions. This is the law under stoichiometry and is also known as Dalton’s law. This law was given by Dalton in the year 1803.
Law of multiple proportions
The Law of multiple proportions states that when two elements combine to form more than one compound, the weights of one element combined with a fixed weight of the other are in a ratio of small whole numbers.
Example
The masses of oxygen combined with a fixed mass of carbon in CO2 and CO are 32 and 16, respectively. These masses of oxygen show a simple ratio of 32: 16 that is 2: 1 to each other.
