Part A: answer all four structured questions (100 marks each). Part B: answer three of the four essay questions (150 marks each). Use R = 8.314 J K⁻¹ mol⁻¹ and the Avogadro constant = 6.022 × 10²³ mol⁻¹. Relative atomic masses are given in the questions where needed. Each question has a model answer showing where the marks go.
