A fully-resourced lesson which guides students through using moles to calculate the mass of a substance in a reaction. The lesson includes a detailed lesson presentation (22 slides) and associated worksheets which are used to check the skills and understanding of the students.
The lesson begins by introducing the students to the three steps involved in a calculating mass question. These skills include calculating the relative formula mass and identifying molar ratios in equations to calculate amounts so time is taken to recap on how this is done before students are given the opportunity to try some progress check questions. A worked example brings these three steps together to guide the students to the final answer. The final task involves 4 questions where students are challenged to apply their new-found knowledge.
This lesson has been written for GCSE students (14 - 16 year olds in the UK)
