Ethanol and methanol form a solution that is very nearly ideal.The vapour pressure of ethanol is 44.5 mm and that of methanol is 88.7 mm at 200C.
(a) Calculate the mole fraction of methanol and ethanol in a solution obtained by mixing 60g of ethanol and 40 g of methanol.
(b)Calculate the partial pressure and the total vapour pressure of this solution and the mole fraction of ethanol in the vapour.
