"WebIf ethanol vapor pressure is 8kPa and atmospheric air is 101 kPa, mole fraction of ethanol in air = 8/(101+8)= 7.34%. Resulting mass fraction of ethanol in air is 11.67% using their molecular weights. So density of ethanol would be (11.67/7.34) times the density of air, equaling 0.119 lb/ft3 - which is the density of ethanol gas at 78C and 1atm. " - Density of ethanol vapour
