Dry air molar mass

WebMar 18, 2024 · The nitrogen pseudo-mass is 0.79 * 28 (nitrogen is diatomic with a molar mass of 28), which equals 22.12. The total pseudo-mass is 28.84, which is the average molar mass of air with the stated composition. Divide the individual pseudo-masses by 28.84 to arrive at 0.233 weight fraction oxygen and 0.767 weight fraction nitrogen. The specific gas constant of a gas or a mixture of gases (Rspecific) is given by the molar gas constant divided by the molar mass (M) of the gas or mixture. Just as the molar gas constant can be related to the Boltzmann constant, so can the specific gas constant by dividing the Boltzmann constant by the molecular mass of the gas. Another important relationship comes from thermodynamics. Mayer's relation relates the specifi…
