Mercury vapor is toxic and a problem because of the relatively high vapor pressure exhibited by liquid mercury under ordinary conditions. Below are Hg vapor pressure data at various temperatures(in oC). From this information, calculate the molar enthalpy of vaporization of liquid mercury. 760 torr is 1 atm. A millitorr is one-thousandth of a torr.
50oC | 12.7 millitorr |
80oC | 88.8 millitorr |
120.5oC | 745.7 millitorr |
140oC | 1845 millitorr |
160oC | 4189 millitorr |
