Neco Model Questions Vol1 2023 Chemistry Question 32
Practice objective / multiple choice question 32 from the 2023 Neco Model Questions Vol1 Chemistry examination.
A polymer is formed by condensation of monomer A (\(\mathrm{C_4H_6O_2}\), molar mass \(102\ \mathrm{g\ mol^{-1}}\)) and monomer B (\(\mathrm{C_2H_4O}\), molar mass \(58\ \mathrm{g\ mol^{-1}}\)) in a 2 : 1 molar ratio. Each A-B linkage releases one molecule of water (\(18\ \mathrm{g\ mol^{-1}}\)). If the average molecular weight of the polymer is \(1.20 \times 10^{5}\ \mathrm{g\ mol^{-1}}\), calculate the average degree of polymerization (number of repeating units).
