Question: : A solution containing 0.1 mol/L of solute A and 0.05 mol/L of solute B is to be separated using a membrane with a molecular

: A solution containing 0.1 mol/L of solute A and 0.05 mol/L of solute B is to be separated using a membrane with a molecular weight cut-off of 10,000 g/mol. The solubility of solute A in the membrane is 0.02 mol/L, and the solubility of solute B is 0.03 mol/L. If the feed flow rate is 5 L/min and the retentate flow rate is 2 L/min, what are the concentrations of solutes A and B in the permeate stream? Assume that the membrane is completely selective and that the solutes do not interact with each other or the membrane.
