A student breaks a thermometer and spills most of the mercury (Hg) onto the floor of a laboratory that measures 15.2 m long, 6.6 m wide, and 2.4 m high. (a) Calculate the mass of mercury vapor (in grams) in the room at 20 degrees celcius. The vapor pressure of mercury at 20 degrees celcius is 1.7x10^-6 atm.
