Answer:

15766

Explanation:

The average molecular weight of the polypropylene = 663419 g/mol.

The mass of the repeating unit , monomer which is propylene = 42.08 g/mol

The degree of polymerization is:

[tex]DP_n=\frac {Total\ molecular\ weight\ of\ the\ polymer}{Molecular\ weight\ of\ the\ monomer}[/tex]

[tex]DP_n=\frac {663419\ g/mol}{42.08\ g/mol}[/tex]

Degree of polymerization = 15766
