Concentration in g/dm3 - AQA GCSE Chemistry Calculation Practice Book

Concentration in g/dm3 is one of those calculations where the maths is simple but the unit conversion trips students up every time. This AQA GCSE Chemistry workbook makes it second nature 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 Concentration (concentration = mass / volume, in g/dm3)

- 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)

Concentration calculations require students to divide mass of solute by volume of solution. The tricky part is converting cm3 to dm3 (divide by 1000) before substituting, since questions often give volume in cm3 but expect the answer in g/dm3.

Common student mistakes this workbook addresses: using volume in cm3 without converting to dm3, confusing mass of solute with mass of solution, dividing volume by mass instead of mass by volume, and leaving the answer without g/dm3 units.

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