In case of air, using the perfect gas law and the standard sea-level conditions (SSL) (air density ρ0 = 1.225 kg/m 3, temperature T0 = 288.15 K and pressure p0 = 101 325 Pa ), we have that Rair = P0 / ( ρ0T0) = 287.052 874 247 J·kg−1·K−1. Then the molar mass of air is computed by M0 = R / Rair = 28.964 917 g/mol.
