Please write down answers clearly and step by step. Thanks

2. An organic solute is to be extracted from a dilute aqueous solution (L phase) using fresh solvent (V phase) with a distribution coefficient of 2. The solvent flow is 1.19 times the solution flow and 99% recovery is required. The countercurrent cascade extraction system is to be used. Given: Xa = 0.2, Xa = 0.166 a. Use the Kremser equation to find the number of ideal stages. b. Use the McCabe-Thiele method to find the number of ideal stages. Label the number of each stage and operating and equilibrium lines
