AQA Combined Science - Quantitative Chemistry

GCSE quantitative chemistry maths workbook with model answers, step-by-step methods and practice questions for tricky calculation topics.

This GCSE quantitative chemistry workbook has been designed to help students build confidence with the maths-heavy parts of the chemistry course.

I have gone through common quantitative chemistry question types and grouped them into clear sections so students can see what the examiner is actually asking them to do. Each section includes a worked example showing the method step by step, followed by practice questions so students can apply the skill independently.

The workbook is ideal for students who struggle with chemistry calculations, including those who find moles, rations, masses and equation-based questions overwhelming. It can be used in lessons, for intervention, revision sessions, homework, tutoring, independent study or exam preparation.

The resource includes practice on topics such as:

• relative formula mass
• calculating percentage by mass of an element in a compound
• avogadro constant
• concentration
• mass, moles and Mr calculations
• limiting reactants
• empirical formula from moles
• finding moles from a change in mass
