Consider spills of 10 L of tetrachloroethene (also known as perchloroethene or PCE). What is the maximum concentration of PCE (in g/m3 ) that you can expect in the air if the PCE is spilled in a 50 m3 room at 25C? The density of PCE is 1.62 g/cm3 and can be assumed to be constant with temperature for this problem. The boiling point of PCE is 121.1C. Use the following data for the vapor pressure (p*L in kPa) of PCE as a function of temperature. Note that 1 atm = 101 kPa.
