Chloroform (1)/methyl ethyl ketone (2) form a solution in vapor liquid equilibrium at 330 K.

The chloroform concentration in the liquid phase is x1 = 0.55. Assuming an ideal gas and an ideal solution of liquids, what are y1 and P (in kPa), to 3 significant figures? if given the liquid solution is no longer ideal. In other words, for x1 = 0.55, what are y1 and P (in kPa), to 3 significant figures assuming an ideal gas?
