Question
An unknown liquid has a heat of vaporization of 39.70 kJ/mole. If the normal boiling
point is 83, what is vapor pressure (in torr) of this liquid at room temperature of 25
degrees C? HINT: Normal boiling point occurs when the vapor pressure of the liquid
is the same as atmospheric pressure (1 atm or 760 mm Hg).
