I am trying to figure out the volume one pound propane would displace at 70 degrees if it is vaporized and stored at 0 psi in a vessel. What will the volume of that vessel be?

Propane expands 270x going from liquid to gas. So figure out the volume of one pound of liquid and multiply by 270.

Google says a pound of liquid propane is 0.24 gallons.

Although, it’s probably more complicated than that, given your specific temperature.

I wasn't referring to stoichiometric combustion of propane and pure oxygen. I was intending on the the non-flamable use of the expansion as my motive force. The temperature of 70 was given to insure it was warm enough to vaporize.
