b) Workers in a 1000 m³ processing room in a plastics factory are exposed to vinyl chloride (C2H3CI) gas, which is emitted when the plastic pellets are heated to make the final products. a) If the air change rate in the room is 0.21/h and the source strength of C2H3Cl is 68 mg/h, what is the steady state concentration of C2H3Cl (in mg/m³ and in ppmv) in the room at 25°C and 1 atm? Assume that C2H3Cl is conservative and that the concentration of the gas in the ambient air is zero. What is the concentration of vinyl chloride gas (in ppmv) in the same room 6 hours after all the machines are turned off at the end of the day?
