EVALUATION

The chapter closes with two evaluation sets covering everything above.

Part I (25 multiple-choice questions) ranges across the whole unit: gas-volume and mole calculations from balanced equations, weighted average atomic mass from isotopic composition, an assertion-reason question testing the Avogadro-number definition, equivalent mass of elements/agents, Avogadro-number-based particle counts, percentage-impurity and mass-balance stoichiometry, redox behaviour and disproportionation identification, oxidation-state ordering in sulphur oxyanions, and conceptual questions on what the Avogadro number actually fixes (versus what it would change if it were different). …
