Answer:
The molar volume of a gas expresses the volume occupied by 1 mole of that respective gas under certain temperature and pressure conditions.
scientists use molar volume to measure gas because it it tells us about volume occupied by gas.
Molar volume
- The molar volume of a gas tell us about volume occupied by 1 mole of that respective gas under certain temperature and pressure conditions.
- At STP(Standard Temperature and Pressure) condition which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm.
- The molar volume of a gas is derived from the ideal gas law PV=NRT
