Using moles to balance equations (HT only)
- The balancing numbers in a symbol equation can be calculated from the masses of reactants and products by converting the masses in grams to amounts in moles and converting the numbers of moles to simple whole number ratios.
Students should be able to balance an equation given the masses of reactants and products.
Students should be able to change the subject of a mathematical equation.
MS 3b Change the subject of an equation
MS 3c Substitute numerical values into algebraic equations using appropriate units for physical quantities
