Question

4pounds of gas occupies 10 cubic feet , what would be its total volume, density and specific gravity?

Answer 1

Total volume as you already mentioned will be  10 ft^3

Density=mass/volume=4/10=0.4 pounds/ft^2

Specific gravity= its density/ water density

                          =0.4 / 62.42796

             now calculate

Answer 2

Its volume is given. 10 cubic feet.

The density is the mass over the volume. I suppose we are to take that 4 pounds is the "mass" of the gas. In which case, the density is 4/10 pounds per cubic feet, or 0.4 pounds per cubic feet.

Specific gravity can then be obtained by dividing the density of the gas with the density of water, which is normally approximated to 62.4 pounds per cubic feet. Thus, the specific gravity of your gas is 0.0064, which of course is a unitless number.
