A rough rule of thumb in polymer solution theory is that a 4 molar aqueous polymer solution will have an osmotic pressure of approximately 100 bar. Is this rule of RT In (x water) ? A 4 thumb in approximate agreement with the expression t=- Vwater molar solution is 4 moles per liter of solution, which approximately contains 55 moles of water. First, show that the mole fraction of water xwater Will be 0.9322. Then use R = 8.314x10-5 bar-m³/mol-K, T = 298.15 K, Vwater = 18.015x10-6 m/mol for the remainder of your calculation.
