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…

Web11.13.1 Water Content of Air Moist or humid air is a mixture of dry air and water vapour. The humidity of air, also known as the absolute humidity or humidity ratio, is a dimensionless parameter defined as: (11.155) where Mw is the mass of water vapour carried by mass Ma of dry air. Humidity is measured using instruments called hygrometers. WebAug 21, 2016 · The atomic / molecular weights are: Nitrogen: 14.0067 x 2 = 28.0134 g/mol (remember it is N 2) Oxygen: 15.9994 x 2 = 31.9988 g/mol (remember it is 02) Argon: 39.948 g/mol. Carbon dioxide: 44.01 g /mol. We know the percentage composition so we can use that to work out the weight of each component: indusind personal loan repayment
