Figure 7. Molecular weight dependence of α and δ.

A, α_g (○), α_p (•) and α_h (□) (in %) plotted as a function of molecular weight on a logarithmic scale. B, δ_g (○), Δδ_p (•) and Δδ_h (□) (in l osmol⁻¹) on a logarithmic scale (left-hand ordinate) are plotted as a function of molecular weight on a logarithmic scale. The number of water molecules contributing the transient hydration during each process was obtained assuming the volume of water to be 18 ml mol⁻¹ (0.03 nm³ per molecule) and is shown on the right-hand ordinate.
