Calculate the molar mass and density of dry

Reference no: EM13698036

Question- Dry air (0% humidity) is approximately 78% N2, 21% O2, and 1% Ar by moles. Calculate the molar mass and density of dry air at 0 °C and 1.0 atm. Assume ideal behavior and use two significant figures in your answers.

It is not a question in the book, so I just need the full solution of deriving!
