Calculate the polydispersity index for the mixture described in the previous problem.

Text Solution

Verified by Experts

The polydispersity index is the ratio of`Mbar(w)`to`Mbar(n)`
Polydispersity index=`Mbar(w)//Mbar(n)….(iv)
Substituting the result the previous problem in (iv) gives
Polydispersity index=`(1.20kgmol^(-1))/(1.18kgmool^(-1))=1.02`
