14.1 % purity of a product and assay calculations

14.2a Percentage yield of the product of a reaction and why not 100% in reality

14.2a % reaction yield and theoretical yield calculations and why you can't actually get 100% yield in practice

14.3 dilution of solutions calculations

14.4 Water of crystallisation in a crystallised salt

14.4 water of crystallisation calculations

14.5 Calculation of quantities required for a chemical reaction

14.5 how much of a reactant is needed? calculation of quantities required, limiting reactant quantities

Above is typical periodic table used in GCSE science-chemistry specifications in doing chemical calculations, and I've 'usually' used these values in my exemplar calculations to cover most syllabuses
