2. (3points, Chapter 2, Problem 2.23) The composition of dry air at sealevel is 78.03% N2, 20.99% O2, and 0.033% CO2by volume. (a) Calculate the average molar mass of this air sample. (b) Calculate the partial pressure of N2, O2, and CO2in atm. (Hint: At constant temperature and pressure, the volume of a gas is directly proportional to the number of moles of the gas. Thus, % by volume
