A comprehensive, exam-ready GCSE Chemistry resource bundle on Quantitative Chemistry, fully aligned to the AQA specification and clearly signposted for Foundation and Higher Tier (H-tagged content throughout).

Lesson PowerPoint (24 slides) covers: the law of conservation of mass and why measured mass can appear to change in open systems; relative formula mass (Mr) with worked examples; percentage mass of an element in a compound; introducing the mole and Avogadro’s constant with an original formula-triangle diagram; moles calculations (mass ↔ moles ↔ Mr); using balanced equations and mole ratios for reacting-mass calculations; limiting reactants; concentration in g/dm³ and mol/dm³; a full titration required practical with an original labelled apparatus diagram (retort stand, burette, conical flask) and method; titration calculations; percentage yield; atom economy; volumes of gases at RTP (24 dm³/mol); a one-page formula summary sheet; exam-style questions; and a plenary.

Differentiated worksheet (Bronze/Silver/Gold/Stretch) with a full answer key, A3 revision mat covering every formula and common mistake, and a 15-question exam booklet (44 marks) with a complete mark scheme — all with Higher Tier content clearly marked (H).
