A flask half-filled with methanol is left un-stoppered. The liquid methanol equilibrates with the methanol vapour in the air inside the flask. Atmospheric pressure in the room is 1 bar. The partial pressure of methanol in the vapour in the flask, at 293 K, is 0.13 bar Calculate the mole fraction of methanol in the vapour above a mixture containing 1 mole of ethanol mixed with 2 moles of methanol, at 293 K, at a pressure of 1 bar, using the value of the 0.13 bar for the vapour pressure of pure methanol at this temperature.
