Problem $1$: Multicomponent $T_{\text{b}\text{u}\text{b}\text{b}\text{l}\text{e}}$ Calculations

Use the Peng$-$Robinson equation of state for mixtures $($PrFug$.$xlsx$)$ to determine the bubble temperature and the vapor composition at $2\mathrm{.}0$ bar pressure for a mixture that has the following mole fractions:

n$-$hexane: $0\mathrm{.}32$

n$-$octane: $0\mathrm{.}25$

isobutane: $0\mathrm{.}43$

Include a copy of your spreadsheet with your answer.
