Mercury is a highly toxic metal. Although it is a liquid at room temperature, it has a high vapor pressure and a low enthalpy of vaporization (294 J/g). What quantity of heat energy transfer is required to vaporize 0.500 mL of mercury at 357 °C, its normal boiling point? The density of Hg (l ) is 13.6 g/mL. Compare this heat energy transfer with the amount needed to vaporize 0.500 mL water. See Table 11.2 for the molar enthalpy of vaporization of H2O.
Two volatile liquids (A and B) form an ideal mixture at 300.0K which just begins to boil at a pressure of 0.3000 atm. The vapor pressure of pure component A is 0.5000 atm and the vapor pressure of pure component B is 0.2000 atm
