Waec Model Questions Vol1 2017 Chemistry Question 34
Practice objective / multiple choice question 34 from the 2017 Waec Model Questions Vol1 Chemistry examination.
A condensation polymer is formed from monomer X (C₂H₄O, M = 44 g mol⁻¹) and monomer Y (C₃H₆O₂, M = 74 g mol⁻¹) in a 1:1 molar ratio, each step releasing one molecule of water (M = 18 g mol⁻¹). A 240 g sample of the polymer is obtained with an overall reaction yield of 80 %. Determine the degree of polymerisation (number of repeating units) in the sample.
