Waec Model Questions Vol1 2021 Chemistry Question 37
Practice objective / multiple choice question 37 from the 2021 Waec Model Questions Vol1 Chemistry examination.
In a condensation polymerisation, monomer A (M = 100 g mol⁻¹) reacts with monomer B (M = 150 g mol⁻¹) in a 1:1 molar ratio, releasing one molecule of water (M = 18 g mol⁻¹) for each repeat unit formed. The reaction is started with 1.00 mol of each monomer. After the reaction, the isolated product contains 120 g of polymer and 40 g of unreacted monomer A. Determine (i) the average degree of polymerisation of the polymer obtained and (ii) the mass of water produced during the reaction.
