2. Determine the concentration (mg/m and ppm) of benzene in a closed room (300 m³) if 3.20 grams are spilled. Assume that it all evaporates instantaneously, and that the air in the room is well mixed. Next, allow the room's air to change once in 20 minutes. How long will it take until the concentration in the room is reduced by 50%? How long until the concentration is below the recommended NIOSH limit (1 ppm)? Note that 1 ppm is equivalent to 3.25 mg/m for benzene.
