Molar Volume of a Gas

Formula

V_m = RT / P

Where:

  • V_m = molar volume (L/mol)
  • R = 0.08206 L·atm/(mol·K)
  • T = temperature (K)
  • P = pressure (atm)

    • At STP (273.15 K, 1 atm), V_m = 22.414 L/mol for any ideal gas.

    Ejemplo Resuelto

    Calculate molar volume at STP (273.15 K, 1 atm).

    1. 01V_m = RT / P
    2. 02V_m = (0.08206 × 273.15) / 1
    3. 03V_m = 22.414 L/mol

    Preguntas Frecuentes

    What is molar volume?

    Molar volume is the volume occupied by one mole of a substance. For ideal gases, it depends only on temperature and pressure, not the identity of the gas.

    Is 22.4 L/mol always correct?

    Only at STP (0°C, 1 atm). At SATP (25°C, 1 bar), the molar volume is about 24.8 L/mol.

    Do real gases have the same molar volume?

    No. Real gases deviate due to intermolecular forces and molecular size. The deviation is quantified by the compressibility factor Z.
