Using the mole concept
Subject: Chemistry
Level: Key Stage 4
Resource type: Whiteboard presentation
Teaching type: Multimedia lesson

Description

At the end of this activity, students should be able to:
– write a chemical equation using the molar interpretation
– solve simple problems using the mole concept
– calculate the mass of products or reactants in a chemical reaction
– calculate the volumes of gaseous products
– solve simple problems using the concept of molarity
– calculate the molarity of an acid or base using acid-base titration.

Additional materials 1. Additional materials Additional materials AQA GCSE Additional Science (4463) Chemistry I. Chemistry 2 3. How much can we make and how much do we need to use? The relative formula mass of a substance, in grams, is known as one mole of that substance. 4. How can we control the rates of chemical reactions? Concentrations of solutions are given in moles per cubic decimetre (mol/dm3 ). Equal volumes of solutions of the same molar concentration contain the same number of moles of solute, ie the same number of particles. Equal volumes of gases at the same temperature and pressure contain the same number of molecules. (Candidates will not be expected to find concentrations of solutions or volumes of ases in this Unit.) AQA GCSE Chemistry (4421) II. Chemistry 2 18.

How can we control the rates of chemical reactions? Concentrations of solutions are given in moles per cubic decimetre (mol/dm3). Equal volumes of solutions of the same molar concentration contain the same number of moles of solute, ie the same number of particles. Equal volumes of gases at the same temperature and pressure contain the same number of molecules. (Candidates will not be expected to find concentrations of solutions or volumes of gases in this unit.) III. Chemistry 3 23. What are strong and weak acids and alkalis? How can we find the amounts of acids and alkalis in solutions? If the concentration of one of the reactants is known, the results of a titration can be used to find the concentration of the other reactant.
