Hi please help:)
Contains the average molecular weight of two chemist N2 and other gas mixtures It is calculated. The first chemist used the correct molecular weight of N2 (28) in the calculation; other on the other hand, it has taken into account 14 which indicates the molecular weight of N2. I. chemist and II. chemist Ace 36.8 and 31.2
It was found. Calculate the molar percentage of N2 in the mixture
