From Wikipedia, the free encyclopedia

The value for the volume of gas per mole is incorrect. The article gives 22.4 liters per mole at STP. The STP article gives standard conditions as 1 bar (100,000 Pa) and 273.15 K. The number of liters per mole (or cubic meters per kg-mole) is RT/P. Using a universal gas constant of 8414.4 J/(kg-mole K) gives RT/P = 22.71 for P = 1 bar and T = 273.15. The 22.4 value applies to 273.15 K and 1 atm = 101325 Pa.
