. A kerosene stove that produces XX mg/hr of carbon monoxide (CO) is used in a closed room with a volume of 100 m³. Fresh air enters the room at

the rate of 10m³/hr and stale air leaves at the same rate. Assuming complete mixing and that carbon monoxide is a conservative pollutant (i.e., does not undergo decay), (a) The steady state CO concentration in air in mg/m³. (b) At 22°C and 1 atm pressure, calculate CO concentration in ppm. How doesthe result compare with the 8-hr national ambient air quality standard(NAAOS) of 9 ppm for CO? (2)the stov e was turned on at 6 p.m. at which n time the air in the room was clean (i.e., the CO concentration0), what would be the CO concentration in mg/m3 in the room at 8 p.m.?
