⦁ What is the mass of air in a room that has dimensions of 10m x 20m x 4 m? Use values from the book to show your work.

agasfer [191]

The mass of an air can be derived from the equation from density, where D=m/v. Multiply each sides by v making the equation m= Dv. Substituting the values for density and volume. m = (1.225 kg/m3)(10x20x4)m3 gives a result of 980 kg.
