please help....

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.
