6. Calculate the effective radius of the Li ion at 25 C from its limiting mobility using the Stokes law. Calculate the approximate number of water molecules in the hydration shell of the Li ion. The crystallographic radius of the Li ion is 60 pm. The viscosity of water at 25oC is 8.91.10-4 Pa. With. The intrinsic volume of a water molecule can be estimated from the parameters of the van der Waals equation.
