Thank you in advance.
The molecular weight of a polymer is MP= 1.00x105 g/mol. Assume 100g of the polymer are dissoved in one liter of water at T=298K. Calculate the mole fraction χP of the polymer. Assume at T=298K water is 55.6M.
Part A. Assume the interaction parameter w=5.00. Assume also that the molar volumes of the solvent and the polymer are related by VP¯=NVS¯ .where N is the number of monomers in the polymer. Calculate the activity coefficient of the solvent γS predicted by Flory-Huggins theory.
γS = ???
Part B Calculate the vapor pressure of water over this polymer solution at T=298K where the vapor pressure of pure water is 2536Pa. Assume the vapor behaves ideally. Give your answer in SI units.
P = ???
Part C. What would the vapor pressure be if you trrated this solution as though it were a regular solution? Assume T=298K and give your answer in Si units.
P = ???

Using the regular solution model, show that oil and water do not mix unless the solution is very dilute. Assume oil is the solute. For hydrocarbon-water mixtures assume w-5 and T-300K. Do oil and water mix if x_av- 0.3? Calculate Delta G_MIX. Is it positive, negative, or zero? How about if x_mi = 0.0001? Do oil and water mix at this concentration of oil? At what mole fraction is the oil in equilibrium with its dissolved form? To solve this...
