Environmental Chemistry

A liter of trichloroethylene is placed in a container open to the air and allowed to evaporate into the room.
MW = 131.4 SG = 1.46 VP = 58 mmHg 1 ppm = 5.37 mg/m3
A. What is the saturation concentration of TCE in ppm?
B. What is the saturation concentration of TCE in mg/M3? [omit mg/M3 from your answer]
C. What is the weight of TCE in mg in the container to be evaporated?
D. What would be the concentration of TCE in mg/M3 if fully evaporated? [ weight in container / volume of the room.
E. What would be the concentration of TCE in ppm if fully evaporated? [weight converted to ppm/volume]
