The molecular weight of a polymer is MP= 1.00x105 g/mol. Assume 100g of the polymer are dissoved in one literof water at T=298K. Calculate the mole fraction χP of the polymer. Assume at T=298K water is 55.6M.
Assume the interaction parameter w=5.00. Assume also that the molar volumes of the solvent and the polymer are related by VP¯=NVS¯VP¯=NVS¯ .where N is the number of monomers in the polymer. Calculate the activity coefficient of the solvent γSγS predicted by Flory-Huggins theory.
Please note: 0.018, 1.02 and 1.00 are both wrong!
