1. Consider gaseous water at 300 K at a pressure of 10.0 Torr.
a. Assuming that gaseous water is ideal, calculate the molar volume and compression factor Z.
b. A sample of water vapor at 10.0 Torr and 300. K has a measured molar volume of 1870.9 L mol-1. Calculate Zreal .
c. The second virial coefficient for water at 300 K is reported as 3 1 1126cm3 mol-1. Calculate the compression factor for gaseous water under these conditions using the virial equation (truncated after the second virial coefficient).
d. Compare Zideal , Zreal , and Zvirial . Comment on the meaning of these values.
2. At 300 K and 20 atm, the compression factor of a gas is 0.86.
a.Calculate the volume occupied by 8.2 mmol of the gas under these conditions.
b.Calculate an approximate value of the second virial coefficient B at 300 K.
