. We can determine the molar mass of air by considering Nitrogen (N2), Oxygen (O2) and Argon (Ar) make up 78%, 21% and 1% of the atmosphere, respectively. The molar masses of nitrogen, oxygen and argon are 14, 16, 40 g/mole. Compute the molar mass of air [(〖molar mass)〗_air=0.78〖(molar mass)〗_(N_2 )+0.21〖(molar mass)〗_(O_2 )+0.01〖(molar mass)〗_Ar] Remember that you have 2 atoms in N2 and O2. (5 points)
