A beaker contains two compartments (A and B) with equal volumes of solution separated by an artificial membrane with a pore size of 24 Angstrom (Å). Explain the net movement of solute if Compartment A has 3% albumin while compartment B has 2% potato starch (albumin diameter = 38 Å; potato starch = 300,000-1000000 Å).
