Standard Molar Volume

What is Standard Molar Volume?

The standard molar volume is the volume occupied by one mole of an ideal gas at standard conditions. At STP (0°C, 1 atm) the standard molar volume is 22.414 L/mol; at SATP (25°C, 100 kPa) it is 24.789 L/mol. This value is used to convert between the volume of a gas sample and the number of moles and is derived directly from the ideal gas law (V = nRT/P).
