Answer to Question #350863 in Physical Chemistry for cookie

Question

Determine the composition of a methanol-ethanol mixture over which the equilibrium vapour pressure is 5.0 kPa. Assume that the mixture is ideal.

(Vapour pressure of pure methanol is 8.9 kPa; vapour pressure of pure ethanol is 4.0 kPa)

Report your answer in terms of mole fraction of methanol as a decimal to 3 significant figures. Do NOT include any words, symbols, units or spaces in your answer.
