$1.$ Estimate the fugacity of liquid benzene at $100$ C and $1750$ mm Hg from the following data

The vapor pressure of benzene at T $=300$C $1350$ mm Hg$.$ The density of liquid benzene at $17=100$ deg $*$ C $790$ kg$/$m and may be considered independent of pressure

The equation of state of the gas phase is given cx $=1+($ax$)/($ax$)$ where $8=8\mathrm{.}5*10^-9$ m$/$mal and is a constant $(201$
