Anyknow know anything about compressed gas cylinders? How many cubic feet does a 40 LB propane cylinder have? Whats a way to figure cubic feet from LBS?

1) From chemical formula and periodic table, add up the atomic weights in the chemical formula to determine the molar mass.
2) Divide the mass of gas you have by the molar mass to get number of moles.
3) Plug number of moles and pressure, temperature conditions into the Ideal gas law, PV = nRT

If you want to work in English units, you'll have to find R, the gas constant, in appropriate units.

4.24 lbs/gal
35.97 cu. ft./gal.
so:
40 lbs divided by 4.24=9.43gals.
9.43 galsx35.97 cu.ft.=339.34 cu.ft.
