1. Your company standards mandate that the polydispersity index for your new polymer processing procedure yield a polydispersity index of less than or equal to 1.15. Your polymer processing ends with 3 fractions, labeled D, E, & F in the table below with the breakdown of different size chains within your new polymer sample. Does your new fabrication method meet that standard? Show all your work and justify your answer (describe the measurement you are comparing and why).    Fraction MW # of Chains Ni*Mi Ni*Mi^2 D 75 25 1875 140625 E 140 100 14000 1960000 F 250 120 30000 7500000 SUM: 465 245 45875 9600625
