A mixture of n-heptane (20.0% by volume) and bone dry air flows through a pipe at 1000.0 gal/h. The pressure gauge on the pipe reads 15.0 psi, while the temperature is 85°C. (a) What is the molar flow rate of the mixture in mol/h? (b) Is the gas saturated - justify your answer in one sentence? If not, at what temperature (°C) will the first drop of liquid n-heptane form? (c) At what operating temperature (°C) will 65% of the n-heptane condense?
An open flask sitting in a lab fridge looks empty, but we know that actually it is filled with a mixture of gases called air. If the flask volume is 4.00 L, and the air is at standard temperature and pressure,
