How To Calculate The Molecular Weight Of Air
How To Calculate The Molecular Weight Of Air . Yet it weighs three times the average molecular weight of air (78% n=14, 21% o=16 and.9% ar=40). Partial pressure of the steam: How is the molar weight of air calculated? Quora from www.quora.com Assume air is 79 mole % nitrogen, 21 mole % oxygen. It was not yet possible to actually “count” atoms or molecules. (78.084 / 100) x 28.0134 = 21.8739 g/mol
