  2. Chemical potential of a dilute solution, the chemical energy is expressed in terms of free energy:

  3. The free energy is composted of water free energy, solute energy, and a mixing entropy term due to possibility of rearranging the solute molecules:

  5. To calculate the mixing entropy (configurational entropy), we first examine the number of ways of distributing the water and solute molecules. Using the lattice model, we have:

  6. Chemical potential of a dilute solution determine the entropy is obtained from Boltzmann entropy formula:
