3. Suppose you have a polystyrene sample which has a molecular weight of about 2 million, according to the label on the bottle. You need to check the validity of this label by intrinsic viscosity measurements in toluene at 35C. The M-H-S constants are K=12.6x10-3 cm/g and a=0.71. What should be the range of polymer concentrations you should study by dilute solution viscometry, in order to accurately measure the intrinsic viscosity
