The mole fractions of the main components of dry air at sea level are XN2 = 0.78, xo2 = 0.21, XAr = 0.0093, Xco2 (a) Find the partial pressure of each of these gases in dry air at 1.00 atm and 20°C....

please help....

Extracted text: The mole fractions of the main components of dry air at sea level are XN2 = 0.78, xo2 = 0.21, XAr = 0.0093, Xco2 (a) Find the partial pressure of each of these gases in dry air at 1.00 atm and 20°C. (b) Find the mass of each of these gases in a 15 ft x 20 ft x 10 ft room at 20°C if the barometer reads 740 torr and the relative humidity is zero. Also, find the density of the air in the room. Which has a greater mass, you or the air in the room of this problem? = 0.0004. %3D
