Question

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.
