Explanation:
Law of Multiple proportion states that when two elements combine to form more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always be ratios of whole numbers.
For example, let us assume 2 molecules CO (carbon monoxide) and CO2(carbon dioxide).
CO= 12gm of carbon + 16 grams of Oxygen.
CO2= 12gm carbon+ 32 grams of Oxygen.
The ratio of the mass of oxygen in the given two compounds is 16:32=1:2.
Thus law of multiple proportions is proved.
