The maximum allowable concentration of carbon monoxide in urban air is 10 mg/m3

Question

The maximum allowable concentration of carbon monoxide in urban air is 10 mg/m3 over 8 hours period. At this level , what mass of carbon monoxide is present in a room that is 2.5m x 15m x 40 m in dimensions? 1 gram = 1000 mg The maximum allowable concentration of carbon monoxide in urban air is 10 mg/m3 over 8 hours period. At this level , what mass of carbon monoxide is present in a room that is 2.5m x 15m x 40 m in dimensions? 1 gram = 1000 mg The maximum allowable concentration of carbon monoxide in urban air is 10 mg/m3 over 8 hours period. At this level , what mass of carbon monoxide is present in a room that is 2.5m x 15m x 40 m in dimensions? 1 gram = 1000 mg

Explanation / Answer

Volume of the Room = Length * Breadth * Height = 2.5m X 15m X 40m = 1500 m^3

Maximum allowable concentration over 8 hours period = 10 mg/m^3

Mass of carbon monoxide present in the room = 10 mg/m^3 * (Volume of room) over 8 hour period

=> 10 mg/m^3 * 1500 m^3

=> 15g over 8 hour period
