A physics lecture room has a volume of 254 m3.
(a) For a gas pressure of 1.00 atm and a temperature of 27.0 oC, use the ideal gas law to estimate the number of air molecules in the room. Assume all the air is N2.
(b) Calculate the particle density - that is, the number of N2 molecules per cubic centimeter.
(c) Calculate the mass of the air in the room.
