A Polymer sample has a triangular distribution function such that: Wi=Ni*10^(-4)-(2*10^-2) for 200<=Ni<=300 and Wi=4*10^(-2)-Ni*10^(-4) for 300<=Ni<=400 If the translational diffusion coefficient of this polymer in cyclohexane at 34.5 centigrade is: D=(1.21*10^-4)*M^(-0.5) then what are Dn, Dw, and Dz? (DÉÏÃæ¶¼ÓÐÒ»ºá) The monomer molecular weight is 100, Use a spreadsheet to do this problem but make some diagrams to show the concept.
