The degree of polymerisation of a homopolymer is
A
the fraction of monomer converted to polymer by mass
B
the ratio of the molar mass of the monomer to that of the polymer
C
the number of chains in one mole of sample
D
the number of repeat units in the chain, equal to polymer molar mass divided by repeat-unit molar mass
Answer: D
