The osmotic pressure of a fraction of poly(vinyl nchloride) in a ketone solvent was measured at 25°C. The density of the solvent (which is virtually equal to the density of the solution) was 0.798 g cm-3. Calculate the molar mass and the osmotic virial coefficient, B, of the fraction from the following data:
c/(g /102cm3)
0.200
0.400
0.600
0.088
1.000
h/cm
0.48
1.2
1.86
