Question:

Industrial representatives claim that the NAAQS for SO2 is so low that one exceeds it if one strikes a simple wooden match in a modest-sized room. Is this true? [1 ft = 30.48 cm, Molar Mass of Oxygen = 16 kg/kmol, Molar Mass of Sulfur = 32 kg/kmol]

(a) Calculate the concentration expected for striking such a match in a room that is 15 ft by 15 ft by 8 ft. A typical 2-inch wooden match contains 2.5 mg of sulfur.

(b) Compare the resulting concentration to the annual average SO2 ambient air quality standard [see the Table below].

Answers: Waiting for your answer; (a) 98 g/m3; (b) waiting for your answer.
