A single molecule of the polymer poly(phenylethene) has a mass of 1.38 × 10-17 g.
This polymer molecule is formed by a polymerisation reaction that joins 80 000 80\,000\,80000 of the monomer molecules together.
Calculate the mass of a single molecule of the phenylethene monomer. Give your answer in standard form.
