Igcse Model Questions Vol1 2020 Chemistry Question 24
Practice objective / multiple choice question 24 from the 2020 Igcse Model Questions Vol1 Chemistry examination.
In a step‑growth polymerisation, a diacid of molar mass \(146\ \text{g·mol}^{-1}\) reacts with a diol of molar mass \(62\ \text{g·mol}^{-1}\). Initially, \(0.500\ \text{mol}\) of each monomer are present. At a certain stage the number‑average degree of polymerisation is measured to be 250. Assuming ideal step‑growth behaviour, calculate the mass of polymer present at that stage (in grams).
