Question

What is gram molar volume?

Answer 1

Gram molar volume:

• The volume that is occupied $1$ mole of an ideal gas at standard temperature and pressure conditions.
• The standard temperature corresponds to $0°\mathrm{C}$, which is $273.15\mathrm{K}$. While the standard pressure can be taken as $1\mathrm{Atm}$.
• The value of the gram molar volume is $22.4\mathrm{L}$.

Example:

• A sample of pure helium gas occupies a volume of $6.8\mathrm{L}$at $0°\mathrm{C}$and $100\mathrm{kPa}$.
