The radius of gyration (Rg) of polystyrene ( M₁ = 3 × 107 g mol−1 ) is 1010 angstroms. Calculate the resulting concentration (in grams per ml and in molar) for close packing of the polymer chains, assuming that each polymer is a sphere of radius Rg, and that the polymers cannot penetrate each other. (For close packing the balls occupy л/(3√2) of the total volume).
