Terminal Relaxation Time in Dilute Solution

A macromolecule of unknown structure but believed to be of uniform molecular weight and unbranched has an intrinsic viscosity of 2500 ml/g in water at 25 C and the molecular weight determined by light scattering is 1.0 X 10 . What is the terminal relaxation time in this solvent  

An estimate can be made from equation 10 of Chapter 9 by taking m = 1. For rigid and semirigid rods, m is near unity for linear flexible coils, m = ST is not
