A fully structured “how to” worksheet designed to support GCSE Combined Science students in mastering one of the most challenging topics: mole calculations.

This resource is ideal for Higher Tier students and carefully scaffolds learning from core skills through to multi-step exam-style questions.

What’s included?

• Step-by-step guided practice questions
• Clear method boxes to support independent learning
• Essential formula reminders (mass, moles, concentration)
• Unit conversion support (cm³ ↔ dm³)
• Exam-style questions progressing from Grade 4 → Grade 9
• Higher tier multi-step problems (including extended calculations)
• Targeted help boxes for more challenging questions
• A full answer sheet with worked solutions for self-assessment

Perfect for:
GCSE Combined Science (AQA 8464) – Higher Tier
Revision lessons or exam preparation
Independent study or homework
Intervention and catch-up sessions
Building confidence in quantitative chemistry skills

Why this resource works - Students often struggle with:

1. Choosing the correct formula
2. Calculating Mr accurately
3. Converting units correctly
4. Structuring multi-step answers

This worksheet breaks each process down into clear, repeatable steps, helping students develop confidence and exam technique.

Skills covered

• Calculating moles from mass
• Calculating mass from moles
