If a polyvinylchloride (PVC) polymer sample elutes on a gel permeation chromatograph column at the same volume as a polystyrene sample that has a molecular weight of 20,000 and an intrinsic viscosity of 2.3 dL/g and the PVC polymer has an intrinsic viscosity of 4.8 dL/g what is the molecular weight of the PVC polymer sample?
