10. For polystyrene in butanone at 67C the following values of Kc/R, 10 were measured at the indicated concentrations and angles. Construct a Zimm plot from the data below using y = 100 mL/g for the graphing constant. Evaluate M, B, and R from the results. In this experiment ^, = 546 nm and n = 1.359 for butanone.

9. Plot the light scattered intensity (arbitrary NE and B with solvent quality. expect to see for a very dilute solution of polysty) versus scattering angle that you would 35C. Assume the instrument has an angulalystyrene with M=4,000,000 in cyclohexane an angular dependence of the intensity if the scar range of 20150. On the same axes show the 10. For polystyrene in butanone at 67C the following object were a hard sphere with the same Rk indicated concentrations and angles Collowing values of K/Ri106 were measured at the y=100mL/g for the graphing constant. experiment 0=546nm and n=1.359 for butanone. 11. Draw a sketch of a complete Zimm-plot for a high molecular weight polymer in a theta solvent, assuming data were acquired at eight angles and at four concentrations. In a different color pen, indicate the effect on the data if a small amount of dust were present in the solution. Similarly, in a different color indicate the effect on the data of naising the solution tcmperature substantially. State any assumptions you make
