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

Mention the volume occupied by one mole of an ideal gas at STP.

For a real gas critical volume (Vc) is '2x' times the actual volume occupied by gas molecules, 'x' value is

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.

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

Calculate the volume occupied by 0.01 moles of helium gas at STP.
