what is the degree of polymerization (DP) of LDPE having an average molecular weight (mass) of 27,980?

Expert Solution

average molecular weight (mass) = 27,980

repeated unit molecular weight = 2 x C + 4 x H

= 2 x 12 + 4 x 1

= 28 g/mol

degree of polymerization (DP) = average molecular weight / repeated unit molar mass

= 27,980 / 28

= 999

degree of polymerization (DP) = 999
