Polyacrylonitrile is an addition polymer made from the acrylonitrile monomer,CH₂CHCN.How many monomer units are in a polyacrylonitrile polymer that has a molar mass of 8.33 × 10⁴ g/mol?

Question

Quizplus · Accepted Answer

The molar mass of acrylonitrile (CH2=CHCN) is approximately 53.06 g/mol. To find the number of monomer units in the polymer, divide the molar mass of the polymer by the molar mass of the monomer: $8.33 \times 10^{14} \, \text{g/mol} \div 53.06 \, \text{g/mol} = 1.57 \times 10^{13}$.
