Achemistry student accidentally drops a large mercury thermometer and it breaks. the thermometer contained 2 grams of mercury (hg), a potent neurotoxin. the hg leaks out and pools together into a droplet on the floor of the laboratory. the occupational safety and health administration (osha) sets the permissible exposure limit (pel) for mercury vapor in air at 12 parts per billion, by volume. at no time should anyone be exposed to mercury vapor above this threshold. the molar mass of hg is 201 g/mol. the temperature and pressure in the lab are 14.7 psia and 70°f, respectively.
