Gce Model Questions Vol1 2025 Chemistry Question 39
Practice objective / multiple choice question 39 from the 2025 Gce Model Questions Vol1 Chemistry examination.
A polymer is formed by condensation of monomer A (C\(_2\)H\(_4\)O\(_2\), M = 60 g·mol\(^{-1}\)) and monomer B (C\(_3\)H\(_6\)O, M = 58 g·mol\(^{-1}\)) in a 2:1 molar ratio. For each repeat unit, two molecules of water (M = 18 g·mol\(^{-1}\)) are released. If the polymer chain contains 100 repeat units, what percentage of the original mass of the monomers is lost as water during polymerisation? Give your answer to one decimal place.
