This International GCSE qualification contains a broad range of topics designed to engage students in chemistry whilst providing the knowledge and understanding required for progression to A-level. Practicals in this specification include investigating factors affecting the rate of a reaction and testing for the presence of a double bond in an unknown hydrocarbon. Exam questions will be asked on the practicals, but there is no coursework or practical exam. These guides were updated in October to reflect the latest specification changes.
This equation shows how relative formula mass , number of moles and mass are related:. This can be rearranged to find the mass if the number of moles and molar mass its relative formula mass in grams are known. It can also be rearranged to find the molar mass if the mass and number of moles are known. The triangle diagram may help you with this.

Which reactant is in excess and which is the limiting reactant? Step 2 Write the balanced equation and determine the molar ratio. Step 3 Compare the moles. So to react completely 0. Na is therefore the limiting reactant.
Introducing the mole, the unit of measurement for the number of particles in a substance. The actual masses of atoms , molecules and ions are too small to be useful in calculations. For this reason, chemical amounts are measured in moles. The mole is a unit. Its symbol is mol.
