A Polydisperse mixture of a polymer can be describe by the following composition-molar mass data:
`{:(Mass%),25.0,50.0,25.0),(Mi(kgmol^(-1)),1.00,1.20,1.40):}`
Calculate the number -average.

To calculate the number-average molar mass (\(M_n\)) of a polydisperse mixture of a polymer, we will follow these steps: ### Step 1: Convert Mass Percentages to Mass in Kilograms Assume we have 100 grams of the mixture. The mass percentages can be converted to grams as follows: - For 25%: \(25 \, \text{g}\) - For 50%: \(50 \, \text{g}\) - For 25%: \(25 \, \text{g}\) ...
