We flash distill a mixture that is \(28.1 \mathrm{~mol} \%\) n-butane, \(42.8 \mathrm{~mol} \% \mathrm{n}\)-pentane, and \(29.1 \mathrm{~mol} \% \mathrm{n}\)-heptane. \(\mathrm{T}_{\text {drum }}=41^{\circ} \mathrm{C}\) and \((\mathrm{V} / \mathrm{F})_{\text {drum }}=0.35\). Find \(\mathrm{p}_{\mathrm{drum}}, \mathrm{y}_{\mathrm{i}}\), and \(\mathrm{x}_{\mathrm{i}}\) values. Use Eq. (2-28).
