The average "molar mass" of dry air under these conditions is 29 g/mol.
In chemistry, the molar mass of a chemical compound is described as the mass of a pattern of that compound divided by way of the amount of substance which is the number of moles in that pattern, measured in moles. The molar mass is a bulk, now not molecular, belongings of a substance.
The molar mass of a compound defines the mass of 1 mole of that unique substance and the range of grams according to the mole of a compound. In other words, the molar mass is the whole mass of all the atoms in grams that make a mole of a selected molecule. consequently, the gadgets of molar mass are grams/mole.
The ideal gas equation,
PV = nRT
number of moles = mass (m) / Molar mass (M)
PV = m/M RT
PM = M /V RT
density = mass / volume
PM = SRT
M = SRT / P
Putting the values, M= 1.26 x 8.31 x 283k / 102.5KPa
= 28.9 g/mol
= 29 g/mol
