A volatile substance evaporates from an open container into a room of volume 28.3 m3. The evaporation rate is 100 mg/min. If the air in the room is assumed to be well mixed, how many m3/min of fresh air must be supplied to ensure that the concentration of the volatile is maintained below its TLV of 100 ppm? The temperature is 25°C, and the pressure is 1 atm. The volatile molecular weight is 100 g/g-mole. Under most circumstances, the air in a room cannot be assumed to be well mixed. How would poor mixing affect the quantity of air required
