asked one$-$at$-$a$-$time.

A phase equilibria experiment with diethyl ketone $(1)+n-$hexane $(2)$ has been performed with the following measurements.

$P=66\mathrm{.}45$kPa,$T=338\mathrm{.}15K,x_1=0\mathrm{.}64,y_1=0\mathrm{.}316$

Vapor pressures are $P_1^{\text{s}\text{a}\text{t}}=29$kPa,$P_2^{\text{s}\text{a}\text{t}}=90\mathrm{.}15$kPa.
