The following T$-$xy equilibrium diagram in Figure $1$ was prepared for an acetone $-$ water mixture at

$P=1$ bar. The temperature in $C$ is shown on the $y-$axis and the equilibrium mole fraction of acetone

is on the x$-$axis. The bubble point and dew point curves are also shown in the Figure. Answer the

following using the attached $T-$xy diagram:

$($a$)$ What are the boiling points of acetone and water?

$($b$)$ For an equimolar feed of acetone and water, estimate the bubble point and dew point

$($c$)$ Estimate the bubble point of a $80$ mole $\%$ acetone $-20$ mole$\%$ water mixture
