The vapor pressure of mercury is 0.0020 mm Hg at 26 °C.
a) Calculate Kc and Kp for the process Hg (l) ?Hg (g).
b) A student breaks a thermometer and spills mercury onto the floor of a lab that measures 6.1 m x 5.3 m x 3.1 m. What is the mass of mercury in grams that is vaporized at equilibrium AND what is the concentration of mercury in mg/m3?
c) Does this concentration exceed the safety limit of 0.05 mg/m3?
