4. The radius of gyration and second virial coefficient of a sample of polystyrene dissolved in cyclohexane were measured at a series of temperatures with the following results T/K 305.7 | 307.2 | 311.2 | 318.2 | 328.2 Rg/nm | 47.9 51.8 57.6 62.5 66.5 B -0.40 -0.20 0.37 0.95 1.58 Estimate the unperturbed root mean square end-to-end distance (empirically) and the O temperature in this solvent. Ro = 130 nm; T = 308 K
