Question
The volume occupied by one mole of gas at STP is known as the ____________.
- Gram molar volume
- Gram atomic mass
- Gram molecular mass
- Gram molal mass
Hint:
Volume of one mole is related to molar volume.
The correct answer is: Gram molar volume
We know,
PV = nRT 
V/n = RT/P
The volume occupied by one mole of gas at STP is known as the gram molar volume.
Molar volume of a gas is defined as the volume of one mole of the gas. Thus, the molar volume is also the volume occupied by 6.023 x 1023 particles of gas.
