The following osmotic pressure data are availabel for a polymer
| c (g/dL-1) | h (cm of solvent) |
| .32 | 0.70 |
| 0.66 | 1.82 |
| 1.00 | 3.10 |
| 1.40 | 5.44 |
| 1.90 | 9.30 |
Given this information and assuming the tempeture is 25 deg Celcius and the solvent density is 0.85 g/cm^3, provide the following:
a) A plot of (rho*g*h)/(RTc) versus concentration, c.
b) The molecular weight of the polymer and the second viral coefficient, A2, for the polymer solution.
