The densities of liquid and gaseous CCl$4$ at $280\backslash$deg C are pg$=0\mathrm{.}7634$x$10^3$ and pl$=0\mathrm{.}3597$x$10^3$ kg$/$m$^3,$ respectively, and at $270\backslash$deg C are pg$=0\mathrm{.}8666$x$10^3$ and pl$=0\mathrm{.}2710$x$10^3$ kg$/$m$^3,$ respectively.

Calculate po and $\backslash$alpha $.$ Since the critical temperature is given as tc$=283,2\backslash$deg C

Calculate the critical density and molar volume of CCL$4$ at the critical point.
