Density of LPG in g/L What is the density of LPG (in vapour state) in g/L?
Please note that I'm asking about the density of vapour LPG when it comes out of the cylinder. NOT the liquefied density!
LPG – propane – gas density is 1.55 times heavier than air. It is  $1.898$ g/L vs  $ 1.225$ g/L for air (both 15°C at sea level).
