For example, oxygen makes up 8/9 of the mass of any sample of pure water, while hydrogen makes up the remaining 1/9 of the mass. formation of water and hydrogen peroxide , carbon dioxide and carbon monoxide are the big examples of law of definite proportion. example Law of Multiple Proportions Problem-Law which states that when elements combine, they do so in the ratio of small whole numbers (assuming they have the same type of chemical bonds).
Two different compounds are formed by the elements carbon and oxygen. The first compound contains 42.9% by mass carbon and 57.1% by mass oxygen. The second compound contains 27.3% by mass carbon and 72.7% by mass oxygen. Show that the data are consistent with the Law of Multiple Proportions.
