(a) Find the number of moles in one cubic meter of an ideal gas at 20.0˚C and atmospheric pressure.
(b) For air, Avogadro's number of molecules has mass 28.9g. Calculate the mass of one cubic meter of air.
(c) State how this result compares with the tabulated density of air at 20.0˚C
The ideal gas law relates the pressure P, volume V, and temperature T of an
ideal gas:
PV = nRT
where n is the number of moles and R = 8.3145 J/(K mol). Plots of pressure
versus volume at constant temperature are called isotherms. Plot the isotherms
for one mole of an ideal gas for volume ranging from 1 to 10 m', at tempera-
tures of T = 100, 200, 300, and 400 K (four curves in one plot). Label the
axes and display a legend. The units for pressure are Pa. n=1
