A sample of poly(ethylene terephthalate), PET, was dissolved in a solvent to give a series of solutions of different concentrations (c). A membrane osmometer was used to measure the corresponding osmotic pressures (pi) at 25 oC. Given that a plot by pi/c vs c gave an intercept equivalent to 94.2 J/kg and the point specified by pi/c = 141 J/kg and c = 8.70 x 10-3 kg/dm3 lies on the plot, evaluate (i) the second virial coefficient (A2), and (ii)...
