The excluded volume (b) is = 4 (volume of one gas molecule)

The ratio of excluded volume ( b ) to molar volume of a gas molecule is

The ratio of excluded volume ( b ) to molar volume of a gas molecule is

Why excluded volume v is four times the actual volume of molecules?

The van der Waals constant b is realted to the volume occupied by the molecules of a gas. It is known as the excluded volume by the molecules of a gas. It is known as the excluded volume or noncompressible volume of the gas. It is equal to ……… times the actual volume of one mole of gas molecules.

Excluded volume for free random motion of gas molecules is how many times the actual volume of gas molecules

The numerical value of b is ......times the actual volume occupied by one mole of gas molecule.

The numerical value of b is ......times the actual volume occupied by one mole of gas molecule.
