Given the different molecular weights, dipole moments, and molecular shapes, why are their molar volumes nearly the same?

a. Because in the gas phase molecules do not interact with each other.

b. Because molecules of a gas have very low kinetic energy.

c. Because these factors compensate each other.

d. Because most of the volume occupied by the substance is empty space.

Brennen Curtis · Answer 1

option d

Explanation:

Molecular sizes of gaseous molecules are very less. Volume occupied by the all the molecules of the gases are very less or negligible as compared to the container in which it is kept. Therefore, most of the volume occupied by gaseous molecules are negligible.

Volume occupied by the gaseous molecules are actually the volume of the container and its does not depend upon the amount, molecular mass or dipole moment of the gaseous molecules.

Therefore, the correct option is d 'Because most of the volume occupied by the substance is empty space.'
