e system during the compression process, which allows the pressure to be increased from 1.5 atm 4.5 atm, is 22 kW. A 2.5 L gas sample was taken to determine the composition of the gas stream ed to the condenser, and this sample was cooled to a temperature that allowed all açetone in it to eparate in liquid form. The mass of the liquid acetone was measured to be 0.875 g. a) Perform a degree of freedom analysis for this system. Show that there is enough data to calculate the composition of all currents and the required heat transfer rate (Q). b) Using the information given in the question, calculate the total moles of the incoming gas mixture, the acetone fraction in the inflow and the acetone fraction in the outgoing gas stream. c) Write equivalences for acetone, air, and energy and create a set of equations. Solve this set with MATLAB or Python.
