Answer 1

What are you solving for?

Answer 2

It seems like you want the mass of air in that room. You already have the density.

First you will have to convert from feet to cm. There are 2.54 cm per inch. Multiply by 12 and you have cm per foot. Now multiply the length width and height of the room to get the volume in cm3.

Now you are in luck as 1 ml = 1 cm3. So you already have the number of ml in the room.

Now multiply by the density of 1.19 g/ml and yu have the mass of air in the room.
