Equations, Moles and Calculations
It is important for chemists to know how much of a chemical is present when a reaction is carried out. Getting it right can mean the difference between a safe reaction and an explosion. The resources on this page are about supporting students’ understanding of inter-converting mass, molar mass and number of moles and ensuring that they are able to use equations quantitatively. Students may also need to be able to calculate or understand the concentration of a solution in moles per cubic decimetre or be able to do calculations involving volumes of gas.
Several will also be relevant to acids, alkalis and titrations.
