Mass transfer question,please clearly solution,thank you

A packed absorption column is to be used to reduce solute A content of a gas mixture of A+B, from 1.5 mole percent to 1 mole percent by washing it with solvent S at 1 bar and 25C. The solvent is not pure and contains 0.2 mole percent solute A. Entering gas stream flowrate is 1kgmol/hr. a) Calculate the minimum molar ratio of liquid to gas (L/G)min. b) Write the operating line equation for an operating L/G ratio which is just in the middle between the range L> and L> minimum; and draw the operating line together with the equilibrium diagram. c) Calculate the ideal number of stages for a tray tower. Equilibrium data at the operating conditions are given below, where x and y are the mole fraction of solute A in liquid and gas
