Question:
Molar volume is the volume occupied by 1 mol of any (ideal) gas at standard temperature and pressure (STP: 1 atmospheric pressure, 0 °C). Show that it is 22.4 litres.

Answer:

The ideal gas equation relating pressure (P), volume (V), and absolute temperature (T) is given as:

PV= nRT

Where, R is the universal gas constant = 8.314 J mol^-1K^-1

n= Number of moles = 1

T= Standard temperature = 273 K

P= Standard pressure = 1 atm = 1.013 × 10⁵Nm^-2

∴ V = nRT / P

= 1 x 8.314 x 273 / 1.013 x 10⁵

= 0.0224 m³ = 22.4 litres

Hence, the molar volume of a gas at STP is 22.4 litres.
