The running engine of an automobile produces carbon monoxide (CO),a toxic gas, at the rate of 199 g CO per hour. A car is left idlingin a poorly ventilated garage that is 6.0 m long, 4.0 m wide, and2.2 m high at 20.0 degrees celsius. How long would it take to buildup a lethal concentration of CO of 1.000 x10^3 ppmv (parts permillion by volume)?
