For the gas with composition given in the table below, please determine: $($a$)$ Apparent molecular weight;

$($b$)$ IUwa $B_w$ without correction for impurities; $($c$)(I_w{)}^{\text{'}},($Pw$)$ for the gas using the Wichert and Aziz $C{O}_2$ and

$H_{2}S$ correction, $($d$)Z$ factor if $T=200F$ and $P=4,750$ psia. $($Use three methods for $Z$ : the chart, DAK and

YH$).$ Do the math on your paper! Show work. Do not just write answers here from the Excel program.
