Solvent molecular weight
WebHere difference is the freezing points depression of the solid. From this freezing dot change, the quantity weight of the solute was calculated. The first trial with 0.5060 g a the solute managed ampere formula height of 87.496 g/mol and the second trial with 1.0126 g of that solution produce a formula weight of 109.017 g/mol. In size-exclusion chromatography, such as gel permeation chromatography, the intrinsic viscosity of a polymer is directly related to the elution volume of the polymer. Therefore, by running several monodisperse samples of polymer in a gel permeation chromatograph (GPC), the values of and can be determined graphically using a line of best fit. Then the molecular weight and intrinsic viscosity relationship is defined.
