It is found that the boiling point of a binary solution of A and $B$ with $x_A=0\mathrm{.}4217$ is $96C.$ At this temperature the vapour pressures of pure A and $B$ are $110\mathrm{.}1$kPa and $76\mathrm{.}5$kPa, respectively. $($i$)$ Is this solution ideal? $($ii$)$ What is the initial composition of the vapour above the solution?
