Use the real-world context of fertilisers in food production to practise applying understanding of reacting masses and gas volumes
As the world’s population increases, the demand for food also increases. This increased demand for food means we need to increase global crop production, often through the use of fertilisers, such as ammonium nitrate, NH4NO3, and ammonium sulfate, (NH4)2SO4. The questions in these worksheets explore these chemicals and ask learners to apply their understanding of reacting mass to this context.

About this resource
These In context worksheets ask learners to use their knowledge of reacting masses and gas volumes in the context of fertilisers in food production, building their confidence and capability to face exam questions. Both the foundation and higher worksheet cover reacting masses, the higher worksheet also includes questions about gas volumes. With a mixture of multiple choice, short and long-answer questions covering:
Foundation level worksheet
- word and balanced chemical equations
- mass of reactants and products
- relative formula mass
- percentage yield
Higher level worksheet
- balanced chemical equations
- relative formula mass
- molar gas volume
- actual yield and theoretical yield
- percentage yield calculations
Learners are supported to practise their mathematical skills and build their confidence. The worksheets are available at foundation and higher level and as fully-editable versions, giving you the flexibility to select the questions most relevant to a particular lesson or group of learners.
