Ask your school for the current course outline and assessment expectations, then share them with your tutor. 02 ### Chemistry 20: topics to discuss Atomic structure and bonding, chemical reactions, quantities in reactions, solutions and gases. Build reliable mole calculations and explain the particle model behind them. Track units through each conversion, balance the equation and use the correct mole ratio. Confirm the current topic sequence and full coverage using your school’s outline and the official source below. 03 ### Building confidence in science A balanced equation gives particle and mole ratios, not a direct mass ratio. Convert mass to moles first, use the stoichiometric ratio, then convert to the quantity requested. Lessons can alternate a modelled example, a question attempted together and an independent attempt so the tutor can see where understanding changes. 04 ### Use school feedback to guide revision Bring a recent question, marked solution or topic checklist. Explain where you got stuck. The next practice task should check that particular skill before introducing more complexity. Tutoring supports learning; assessed submissions remain the student’s own work. Understand it. Try it. Review it. ## Put your science learning into practice. Worked example · Moles, reactions and solutions ### Find the amount in 9 g of water. Use molar mass 18 g/mol. 1. Use n = m/M. 2. n = 9/18 = 0.5. 3. There are 0.5 mol of water. Common mistakes to check - Changing subscripts to balance an equation - Using millilitres in a concentration formula that requires litres [Preview the worksheet](https://nobleeducators.com/learning-worksheets/chemistry-practice.pdf) Free PDF · 6 activities · Answers included ### Moles, reactions and solutions Senior secondary chemistry.
