The density of air at ordinary atmospheric pressure and 25 ∘C is 1.19 g/L. What is the mass of the air in a room that measures 13.5×17.5×7.0 ft?

Answer 1

here's a partial solution.....

The volume is 13.5 * 17.5 * 7 = 1653.75 cubic feet

The density is partially in metric, not sure what the temperature has to do with it...

density = mass / volume

mass = density * volume = D * volume where D is the converted density
