Calculate the molar volume of saturated liquid and the molar volume of saturated vapours for the Propaneat $40\backslash$deg C$,$ where Psat $=13\mathrm{.}71$ bar, using the following:$($a$)$ Ideal Gas Equation$($b$)$ Redlich$/$Kwong equation$($c$)$ Redlich$-$Kwong$-$Soave$($d$)$ Peng$-$Robinson$($e$)$ The Pitzer generalized compressibility$-$factor correlation.

I need the calculation with the answer $)))$
