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

Molar concentration adds another layer to the concentration calculation students already know, and the jump from g/dm3 to mol/dm3 catches many off guard. This AQA GCSE Triple Chemistry workbook builds 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 Concentration in mol/dm3 (concentration = moles / volume)

- 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 (Triple Chemistry only)

Molar concentration calculations require students to calculate moles of solute (often from mass and Mr), then divide by volume in dm3 to find concentration. Students also convert between g/dm3 and mol/dm3 using Mr as the conversion factor.

Common student mistakes this workbook addresses: using volume in cm3 without converting to dm3, confusing the g/dm3 formula with the mol/dm3 formula, not calculating moles before dividing, and mixing up the conversion direction between the two concentration units.

Suitable for AQA GCSE Chemistry (Triple only, not Combined Science). Works for both foundation and higher tier students.
