Ethanole and methanol form a solution that is very nearly ideal. The vapour pressure of ethanol is `44.5`mm and that of methanol is `88.7mm` at `20^(@)C`
(a) Calculate the mole fraction of methanol and ethanol in a solution obtained by mixing 60g of ethanol with 40g of methanol.
(b) Calculate the partial pressure and the total vapour pressure of this solution and the mole fraction of ethanol in the vapour.

Answer

(a) `0.49,0.51` (b) `22.7,43.5`, `0.34`
