A sealed bottle of 'hard lemonade' (lemonade with alcohol in it) is in a liquid-vapour equilibriumstate at 298.15 K. The liquid phase contains 250 mL of 5.40% alcohol (v/v) (meaning that for every100 mL of solution, 5.4 mL is pure ethanol) The number of moles of solution in the vapour phase isone tenth the number of moles of the liquid phase and the ethanol composition of the vapour phase is0.735. It is also known that the density of water is 1.000 g/mL (M.W. = 18.015 g/mol) and thedensity of ethanol is 0.789 g/mL (M.W. = 46.07 g/mol). What is the total composition, (z) forethanol in this system? You can ignore the effects of the sugar and other components in this mixtureand treat the solution as an ideal water-ethanol solution.
