Suppose polyethylene molecules in a solution can exist in either a random-coil conformation or in a fully stretched-out conformation. The stretched-out conformation is 2.4 kJ/mol higher in energy than the random-coil conformation. What percentage of molecules are in the stretched-out conformation at 20 degrees Celsius?
Calculate the mass of the solvent (CCl4) in kg. Use the molality calculated in question 2 and the solvent mass calculated in question 3 to determine the number of moles of solute present in this solution.
