Question one: Assume that dry air consists of only 20.00% oxygenand 80.00% nitrogen by volume.
What is the density of dry air at 0.90030 atmand 22.31 ∘C?
Answer in g/L to four significant figures.
Question two: A flask has a volume of 148.5 mL . When filledwith air at a pressure of 834.6 torr and a temperature of 24.74 ∘C,the flask and air have a mass of 67.887 g . When filled with carbondioxide at the same temperature and pressure, the mass of the flaskand CO2 is 67.992 g .
Part A - What is the mass of the carbon dioxidegas in the flask (when the flask is filled with carbondioxide)?
