Answer
Atomic mass of A = MA
Atomic mass of B = MB
Since the formula of the compound is AB, one atom of A combines with one atom of B.
∴ MA : MB = 3 : 8
or,
On cross-multiplication,
8MA = 3MB
Thus, the relationship between the atomic masses of A and B is
8MA = 3MB

Atoms being extremely small, cannot be seen or weighed directly. But indirect methods of physics have enabled us to know the absolute mass of nearly all kinds of atoms. The mass of a hydrogen atom is found to be 1.66 × 10-24 g while that of a carbon atom is 1.9926 × 10-23 g. As these masses are too small, it is not convenient to use kilograms or grams as unit. It has, therefore, been considered appropriate to use the mass of some standard atom as a unit and then relate masses of other atoms to it.
