Construct, as complete as possible a $($p$,$x$)$ diagram for n$-$butane and n$-$heptane at T$=110$oC$.$ Estimate the vapor pressure of these two components $($if it exists$)$ at T$=110$C$.$Provide the graph and the data used to make it$.$Using the data from the $($p$,$x$)$ diagram you have just generated provide: the fraction of vapor fv and the equilibrium gas and liquid compositions for a mixture at p$=($pb$+$pd$)/2...$ where pb and pd are the bubble and dew point pressures at T$=110$oC and z$1=0\mathrm{.}6.$
