part c and d, please!

The exit gas from an alcohol fermenter consists of an air-CO2 mixture containing 9 mol% CO2 that is to be absorbed at steady state using a 5.0-N solution of triethanolamine, which initially contains 0.03 moles of carbon dioxide per mole of amine solution. If (i) the column operates isothermally at 25 C, (ii) the exit liquid contains 72.3% of the CO2 in the feed gas to the absorber, and (iii) absorption is carried out in a five-theoretical-plate column, use the graphical method to calculate: Equilibrium Data Y 0.003 0.008 0.015 0.023 0.032 0.043 X 0.01 0.02 0.03 0.04 0.05 0.06 Y 0.055 0.068 0.083 0.099 0.12 X 0.07 0.08 0.09 0.10 0.11 a. The exit gas composition. b. Moles of amine solution required per mole of feed gas. c. For this part only, given that the moles of amine solution/mole of feed gas is equal to 2.0, what is the exit gas composition? Assumption (ii) from the problem statement no longer applies to this part. d. Based on the exit gas composition that you calculated in part (c), how much of the CO2 from the feed gas ends up in the exit liquid
