a$)$ Estimate the fugacity and fugacity coefficient of n$-$Pentane liquid at its normal boiling pointtemperature and $200$ bars.$($a$)$ Liquid cyclopentane at $110\backslash$deg C and $275$ bars. At $110\backslash$deg C the vapor pressure $($saturated pressure$)$of cyclopentane is $5\mathrm{.}267$ bar. Estimate fugacity and fugacity coefficient.$($b$)$ From data in the steam tables, determine a good estimate for f$/$fsat for liquid water at $150\backslash$deg Cand $150$ bars, where fsat is the fugacity of saturated liquid at $150\backslash$deg C$.$
