A liquid mixture of components A $(44\%$ mole$),$ B $(28\%$ mole$)$ and C $(28\%$ mole$)$

is vapourised at a total pressure of $101\mathrm{.}33$ kPa. Calculate i$)$ the bubble point and

the vapour composition ii$)$ the dew point and the liquid composition. State the

assumptions, if any. The vapour pressure data is as given below:
