A beaker containing 1L of water is divided into two equal compartments by a semi-permeable membrane. One side of the membrane has 1M NaCl solution and the other side is pure water. Determine the time taken for the concentration of NaCl on both sides of the membrane to become equal through diffusion. Given: Molecular weight of NaCl is 58.44 g/mol, and diffusion coefficient of NaCl in water is 1.6 x 10^-9 m^2/s.
