Problem: Mercury (Hg) vapor is toxic and readily absorbed from the lungs. At 20.°C, mercury (ΔHvap = 59.1 kJ/mol) has a vapor pressure of 1.20 x 10−3 torr, which is high enough to be hazardous. To reduce the danger to workers in processing plants, Hg is cooled to lower its vapor pressure. At what temperature would the vapor pressure of Hg be at the safer level of 5.0 x 10−5 torr?
