Chemical Calculations and Moles

GCSE chemistry equations, formulae and calculations are often the part of the syllabus that many students struggle with. From understanding Avogadro’s constant, to mole calculations, formula’s for percentage yield and atom economy, at first this part of the GCSE chemistry syllabus seems very difficult. However, with plenty of revision, memorising of the formula’s becomes easier, understanding atom economy becomes second nature and applying Avogadro’s constant will become straight forward.
