The vapor presurre of mercury is 0.00185 mmhg at 25 degree C. A single drop of Hg(0.1 mL) is spilled in a laboratory of dimensions 10m x 10m x3m. Does the entire drop evaporate? What is the partial pressure of Hg in the laboratory? (Use 13.6 g/ml for the density of Hg.) (b) The normal boiling point of mercury is 630 K. Caluculate an approimate value for vapor pressure.
