The second, B, and third, C, virial coefficients have been studied extensively and tabulated for many fluids for more than a century. Two of the most extensive compilations are in the books by Dymond. and NIST Thermo Data Engine Database and its Web Thermo Tables. Tables of second and third virial coefficients of many fluids are included in these compilations. WebThe first virial coefficient is (4.6) For dilute macromolecule solutions, Eq. (4.5) can be simplified as (4.7) or (4.8) This form suggests that the plot of versus c should be a straight line, and from the intercept and slop of which, we can obtain the molecular weight and the second virial coefficient.
