The normal boiling point of mercury (Hg) is 356.7 °C. What is the vapor pressure of mercury at 326 °C? (ΔHvap = 58.51 kJ/mol)
Boiling mercury is often used in diffusion pumps to attain a very high vacuum; pressures down to $10^{-10} \mathrm{~atm}$ can be readily attained with such a system. Mercury vapor is very toxic to inhale, however. The normal boiling point of liquid mercury is $357^{\circ} \mathrm{C}$. What would be the vapor pressure of mercury at $25^{\circ} \mathrm{C}$ ?
Mercury is the only metal that is a liquid at room temperature. When mercury vapor is inhaled, it is readily absorbed by the lungs, causing significant health risks. The enthalpy of vaporization of mercury is 59.1 $\mathrm{kJ} / \mathrm{mol}$ . The normal boiling point of mercury is $357^{\circ} \mathrm{C}$ . What is the vapor pressure of mercury at $25^{\circ} \mathrm{C} ?$
