Moles Calculations - AQA GCSE Chemistry Calculation Practice Book

The moles formula underpins everything in quantitative chemistry, and students who are shaky on it will struggle with every calculation that follows. This AQA GCSE Chemistry workbook builds rock-solid fluency with 12 scaffolded questions using the EVERY method framework.

The EVERY method breaks each calculation into clear steps: Equation, Values, Enter values into the equation, Rearrange if needed, Your units. Every question has a structured EVERY table for students to complete, building a consistent problem-solving habit. Questions get progressively harder: Q1-3 are straightforward, Q4-6 introduce unit conversions, and Q7-12 require rearranging the formula.

What's inside:

- 12 progressive questions on Moles (moles = mass / Mr)

- Structured EVERY method table on every question page

- Progressive difficulty: simple substitution, then unit conversions, then rearranging

- Self-assessment tracker with "What made me stuck?" reflection checklist

- Full worked answers for all 12 questions using the EVERY method steps

AQA specification reference: 5.3 Quantitative Chemistry (Combined Science and Triple Chemistry)

Moles calculations require students to use mass and relative formula mass to find the number of moles, then rearrange to find mass or Mr. This formula is the starting point for concentration, reacting masses, gas volume, and titration calculations.

Common student mistakes this workbook addresses: dividing the wrong way round (Mr / mass instead of mass / Mr), not calculating Mr before substituting, using grams when the question gives kilograms, and leaving the answer without "mol" as the unit.

Suitable for AQA GCSE Combined Science and Chemistry (Triple). Works for both foundation and higher tier students.
