Webmole-mass calculation. , where we start with a given number of moles of a substance and calculate the mass of another substance involved in the chemical equation, or vice versa. For example, suppose we have the balanced chemical equation: 2Al + 3Cl 2 → 2AlCl 3. Suppose we know we have 123.2 g of Cl 2. WebChemical 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.
