From your data, calculate the density of CO2 (g). Calculate the ratio of the density of CO2 (g) to the density of air at the temperature and pressure measured. How does this compare to the ratio of the molar mass of CO2 to the average molar mass of air? (28.8 g/mol) Calculate the volume of a gas sample at T = 35.0 °C and P = 675 torr if the same sample occupied 42.6 L at T = –27.3 °C and P = 1.000 atm.
