Balanced chemical equation gives number of molecules that react to form products.

Interpretation: ratio of number of moles of reactant required to give the ratio of number of moles of product.

These ratios are called stoichiometric ratios.

NB: Stoichiometric ratios are ideal proportions

Real ratios of reactants and products in the laboratory need to be measured (in grams and converted to moles).
