At normal temperature and pressure, air has

a density of 0.001184 g/mL. What is the mass
of air in a room that is 3.71 m by 3.60 m by
2.51 m?
Answer in units of kg

1 answer

I would change the dimensions to cm, find the volume (371 x 360 x 251) in cubic centimeters, use density to convert to grams, then convert to kg. Remember cubic centimeters (cc) = mL.
