Variables Used
Polydispersity Index - Polydispersity Index is a measure of the distribution of molecular mass in a given polymer sample.
Weight-Average Molecular Weight - (Measured in Kilogram Per Mole) - The Weight-Average Molecular Weight measuring system includes the mass of individual chains, which contributes to the overall molecular weight of the polymer.
Number-Average Molecular Weight - (Measured in Kilogram Per Mole) - The Number-Average Molecular Weight is a measuring system that requires counting the total number of molecules in a unit mass of polymer irrespective of their shape or size.
STEP 1: Convert Input(s) to Base Unit
Weight-Average Molecular Weight: 27 Gram Per Mole --> 0.027 Kilogram Per Mole (Check conversion here)
Number-Average Molecular Weight: 13 Gram Per Mole --> 0.013 Kilogram Per Mole (Check conversion here)
