14.1 A polymer solution was cooled very slowly until phase separation took place to give two phases in equilibrium. Subsequent analysis of the phases showed that the volume fractions of polymer in the phases were = 0.89 and 2 = 0.01, respectively. Using the equation for AG₁ given in Problem 10.1, together with the equilibrium condition AG=AG, calculate an estimate (two significant figures) of the Flory-Huggins polymer-solvent interaction param- eter for the conditions of phase separation.

Solution 1 is diluted by adding 519 microliters of Solution 1 to 5 mL of Solution 2. What is the dilution of Solution 1? Report your answer in standard decimal notation rounded to 2 decimal places. Include trailing zeros so that two decimal points are reported. For example, 500 μL added to 5 mL would be a 0.09 dilution or 50 μL added to 4.5 mL would be a 0.10 dilution.
