Carbon monoxide (CO) detectors sound an alarm when peak
levels of carbon monoxide reach 100 parts per million (ppm).
This level roughly corresponds to a composition of air that
contains 400,000 mg carbon monoxide per cubic meter of air
(400,000 mg/m3). Assuming the dimensions of a room are
18 ft 3 12 ft 3 8 ft, estimate the mass of carbon monoxide in
the room that would register 100 ppm on a carbon monoxide
