The following data are obtained when dinitrogen and dioxygen react together to form different compounds:

Which law of chemical combination is obeyed by the above experimental data ?

Options

A. Law of conservation of mass
B. Law of definite proportions
C. Law of multiple proportions
D. Avogadro's law

Answer

C

Explanation

According to the law of multiple proportions, "if two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element, are in the ratio of small whole numbers."
Fixing the mass of dinitrogen as 28g , masses of dioxygen combined will be 32, 64, 32 and 96 in the given figures. They are in the ratio of 1:2:1:3.
