What is the vapor pressure of ethanol & water of this wine, & what is the mol fraction of these comp in vapor?
The vapor pressure of ethanol at 40 degree is about 135 mm Hg, and the vapor pressure of water at 40 degree is 55 mm Hg. A sample of wine at this temperature has a mole fraction of ethanol of 0.10 and a mole fraction of water of 0.90. What is the vapor pressure of ethanol & water of this wine, & what is the mol fraction of these comp in vapor?
