The vapor pressure of liquid methanol, CH3OH, is 100 mm Hg at 294 K. A 5.59×10-2 g sample of liquid CH3OH is placed in a closed, evacuated 490 mL container at a temperature of 294 K. Calculate what the ideal gas pressure would be in the container if all of the liquid methanol evaporated in mm Hg Assuming that the temperature remains constant, will all of the liquid evaporate? What will the pressure in the container be when equilibrium is reached in mm Hg?

The vapor pressure of liquid octane,
C8H18, is
100. mm Hg at 339 K.
A sample of C8H18 is
placed in a closed, evacuated 552 mL container at
a temperature of 339 K. It is found that all of
the C8H18 is in the vapor
phase and that the pressure is 68.0 mm Hg. If the
volume of the container is reduced to 350 mL at
constant temperature, which of the following statements are
correct?

Use the Clausius–Clapeyron equation to calculate the molar
enthalpy of vaporization of diiodomethane and its normal boiling
point.
*Important you are finding molar enthalpy in kj/mol and finding
normal boiling point in K.*
Find Molar enthalpy = ? kJ/mol
Find Normal boiling point =? K
