Lpg is a useful fuel in rural locations without natural gas pipelines. a leak during the fill- ing of a tank can be extremely dangerous because the vapor is denser than air and drifts to low elevations before dispersing, creating an explosion hazard. what volume of vapor is created by a leak of 40l of lpg? model the liquid before leaking as propane with l  0.24 g/cm3. what is the mass density of pure vapor propane after depressurization to 293 k and 1 bar? compare with the mass density of air at the same conditions.
