Agas mixture containing $80\mathrm{.}0$ mole $\%N_2$ and the balance $n-$hexane flows through a pipe at a rate of $100\mathrm{.}0\frac{m^3}{h}.$

The pressure is $2\mathrm{.}00$atm absolute and the temperature is $120\mathrm{.}0C.$

a$.$ What is the molar flow rate of the gas?

kmo$\frac{l}{h}$

b$.$ To what temperature would the gas have to be cooled at constant pressure in order to begin condensing

hexane?

$C$

c$.$ To what temperature would the gas have to be cooled at constant pressure in order to condense $80\mathrm{.}0\%$ of the

hexane?

These are both dew$-$point calculations. For part c$,$ one just has to do a small mass$-$balance calculation.
