Use the results of Exercises 14.3.3 to evaluate eqn (14.3.9) at Q= 0 for a uniform silica particle in H20. Show how a measurement of this intensity can be used to find the mass of the particle. Does the result depend on particle shape? [Note that this procedure can be used to evaluate the molar mass of any particle, e.g. a protein in dilute solution.]
