1. Convert the units.
(how many ft.cubed. = how many meters cubed)
2. How much space is there, based on above ?
(in meters cubed)
3. Concentration
(micrograms divided by meters cubed x the number of
meters = total amount of CO)
4) How many micrograms is in one gram?
Convert micrograms to grams.
You then have your answer!
Good Luck!
;-)

Your mass is given in cubic meters, your room dimensions are in cubic feet. I'd convert the room dimensions to meters, get the volume of the room in cubic meters, and multiply that answer by your density.
1 meter = 3.28 feet
Come On!! You didn't think I'd give you the answer to the problem did you?! Ha!!

Hint. convert the feet to meters first. Do that and it looks ready to cube, and that should make the further procedure obvious.
