. A gas mixture containing 85.0 mole% N2 and the balance n-hexane flows through a pipe at a rate of 100.0 m/h. The pressure is 2.00 atm absolute and the temperature is 100C. (a) What is the molar flow rate of the gas in kmol/h? (b) 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? (c) To what temperature (C) would the gas have to be cooled at constant pressure in order to condense 80% of the hexane
