Molar Volume vs Temperature (T)
Fórmula
## 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).
- 01V_m = RT / P
- 02V_m = (0.08206 × 273.15) / 1
- 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.
