What is the mass in grams of carbon monoxide present in a room measuring 10.0 x 17.0 x 8.25 ft.?

Question

The concentration of carbon monoxide in a dormitory room is 46.7 mg/m3.

Answer 1

You must be inhaling too much of it and it's making you do math WHY DON'T YOU GET OFF THE COMPUTER AND GET OUT OF THE BUILDING!!! geeks (shaking head in shame) can't help being geeks:( LOL

Answer 2

10.0 x 17.0 x 8.25  = 1402.5 cu ft

1402.5 cu ft @ 0.02832 cu metre/ cu ft =  39.71 m3

===========

39.71 m3 @ 0.0467 grams / m3 = 1.85

your answer is 1.85 grams

Answer 3

Formula for concentration is:

Concentration=Mass/Volume

The volume of the room is 39,72 m3. It is multiplied with the concentration of CO in the room (46.7 mg/m3) and from that the mass of CO is 1.854gr.
