The method of choice for determining the molecular weight of polymer is:

Answer»

Osmotic pressre
Gas density
LOWERING of FREEZING point
Direct weighing of a single molecule

Solution :Osmotic pressure method is best for the determination of molecular weight of polymers and Proteins since`O.P.`through very small,It measurable On the other hand,in other colligative properties (e.g.,DeltaT_(B),DeltaT_(F),Deltap//p^(@)`methods),The difference is very small and cannot be measured.Moreover ,in `O.P.`method ,heating is not required while in other methods,heating is required which CHANGES the properties of polymer and proteins.
