Agas mixture containing 85.0 mole% n2 and the balance n n-hexane flows through a pipe at a rate of 100.0 m3/h. the pressure is 2.00 atm absolute and the temperature is 100°c. what is the molar flow rate of the gas in kmol/h? is the gas saturated? if not, to what temperature (°c) would it have to be cooled at constant pressure in order to begin condensing hexane? to what temperature (°c) would the gas have to be cooled at constant pressure in order to condense 80% of the hexane?
