Methanol and ethanol from nearly an idea...

Methanol and ethanol from nearly an ideal solution. If the vapour pressure of pure methanol and ethanol at `350 K are 8.1xx10^(4)and 4.5xx10^(4)Nm^(-2)` respeclate the total vapour pressure of the solution and the mole fraction of methanol in the vapour phase if the solution contains 64 g of methanol and 46 g of ethanol at this temperature.
