A dilute salt water solution has an osmotic pressure of 5 atm at 15 degrees C. Calculate the difference between the chemical potential of the water in the solution and that of pure water. Assume that the density of the solution is the same as that of pure water. The volume of the solution is 1 liter. The density of water is 1 g/cm3. Hint: since the solution is dilute, we can approximate by saying the volume of the solution is the entirely comprised of water
