Percentage Yield Calculations Worksheet with Answers | AQA GCSE Chemistry

Students know the percentage yield formula but consistently lose marks by confusing actual yield with theoretical yield. This AQA GCSE Chemistry calculation practice workbook builds exam-ready confidence with 12 scaffolded practice questions using the EVERY method framework.

The EVERY method framework breaks each calculation into clear, manageable steps:

• Equation: Write down the correct formula
• Values: Identify and extract the numbers given in the question
• Enter values into the equation: Substitute numbers accurately
• Rearrange if needed: Isolate the unknown variable correctly
• Your units: Double-check final units and rounding

Every percentage yield science worksheet page features a structured EVERY method table for students to complete, building a consistent, high-scoring problem-solving habit for exams.

Worksheet Progression

• Questions 1 to 3: Straightforward substitution into the percentage yield formula
• Questions 4 to 6: Intermediate calculations introducing unit conversions
• Questions 7 to 12: Advanced questions requiring rearranging the formula

What is Included

• 12 progressive chemistry calculation practice questions on Percentage Yield
• Structured EVERY method table on every problem-solving page
• Progressive difficulty covering simple substitution, unit conversions, and formula rearrangement
• Self-assessment tracker with a What Made Me Stuck reflection checklist
• Full worked solutions for all 12 questions using EVERY method steps
• Full alignment with AQA Quantitative Chemistry specification reference 5.3 for Combined Science and Chemistry (Triple, Higher Tier)

Percentage yield calculations require students to compare the mass of product actually obtained with the maximum mass predicted by the balanced chemical equation. This practice booklet helps students explain why practical yield is always less than 100 percent by linking results to incomplete reactions, side reactions, and practical losses.

Key Misconceptions Addressed

• Putting theoretical yield on top instead of actual yield
• Forgetting to calculate theoretical yield from the balanced equation first
• Accepting yields over 100 percent without checking calculations
• Confusing percentage yield calculations with atom economy
