A gas mixture containing 80.0 mol% N2 and the remainder n-heptane flows through a pipe at a rate of 10.0 m3/h. The pressure is 0.90 atm and the temperature is 100°C. a. What is the molar flow rate of the gas in mol/h? b. Is the gas saturated? If not, to what temperature (°C) would it have to be cooled at constant pressure to begin condensing heptane? c. To what temperature (°C) would the gas have to be cooled at constant pressure to condense 75% of the heptane?
