An aqueous solution of methanol in water has vapour pressure

An aqueous solution of methanol in water has vapour pressure:

Ethanol (C_(2)H_(5)OH , M=46) and methanol (CH_(3)OH, M= 32) form an ideal solution when mixed. What is the vapour pressure of a solution prepared by mixing equal masses of ethanol and methanol ? (The vapour pressure of ethanol and methanol are 44.5 mm Hg and 88.7 mm Hg, respectively.)

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.
