The experimentally measured vapor pressures of liquid Hg at four temperatures are listed in the following table: t /C 80 100 120 140 p/Pa 10 45 85 210 From these data, calculate the enthalpy of vaporization (Hvap) of mercury and calculate the boiling point of mercury at 1 atm pressure! Compare your calculations with literature data: Hvap= 59.11 kJ/mol tbp= 356.7 oC. Hint: Use the Clausius - Clapeyron equation!
