Dew$-$point Calculation$-$CLASSEXAMPLE$4$

Find the dew point temperature of a mixture containing $36\mathrm{.}28$ moles of $n-$butane, $48\mathrm{.}25$ moles of $n$ pentane and $15\mathrm{.}47$ moles of $n-$hexane if the pressure is $2$atm. The Antoine vapor pressure constants are: $LnP=A-\frac{B}{T+C}$

n$-$butane $($i$)$: $A=15\mathrm{.}6782,B=2154\mathrm{.}9,C=-34\mathrm{.}42$

n$-$pentane $(j)$:$A=15\mathrm{.}8333,B=2477\mathrm{.}07,C=-39\mathrm{.}94.$
