1. Determine Hvap for a compound that has a measured vapor pressure of 24.3 torr at 273 K and 135 torr at 325 K.

2. Determine the Vapor Pressure (in mmHg) of a substance at 29*C whose normal boiling point is 76*C and has a Hvap of 38.7 kJ/mol

3. Determine the radius of an Al atom (in pm) if the density of aluminum is 2.71 g/cm^3. Aluminum crystallizes in a face centered cubic structure with an edge length of 2v2 r.

4. How much energy must be removed from a 125 g sample of benzene(molar mass = 78.1g/mol) at 425.0K to liquify the sample andlower the temperature to 335.0 K? The following physical datamight be useful:
?Hvap = 33.9 kJ/mol
