Here's another way to do it:

A mole of any gas occupies 22.4 liters at STP so we need to find the volume in liters:

1 ft^3 = 28.32 liters, so the volume is;

10 ft^3 x 28.32 liters/ft^3 = 283.2 liters

The molar mass of acetylene is:

[(2 x 12.01) + (2 x 1.01)] = 26.04g/mole

So, solving for mass of the acetylene;

26.04g/mole x 283.2L/22.4l/mole = 329.1 g or 0.725 lb

The Specific Gravity of Acetylene is 0.9.
The Density of Air is 0.08lb/ft³.
0.08lb/ft³ x 0.9 x 10ft³ = 0.72lbs
