The distance between gas molecules is very large, and a large part of the space between two gas molecules is empty, and the volume of a gas is the space filled by a gas, and the volume of a gas is much larger than the volume of the gas molecules. volume of the gas molecules.

By the density formula ρ=m/v

The density of a gas is much less than the density of the gas molecules

The density of a gas is much less than the density of the gas molecules.
