Mole Ratio from Chemical formulas

The mole ratio is the ratio of any two compounds' mole amounts that are present in a balanced chemical reaction. The balancing chemical equation provides a comparison of the ratios of the molecules needed to complete the reaction. We are unable to determine the mole ratio for an unbalanced equation. The molar ratio of the two reactants is plotted against a solution characteristic while the concentration of one reactant is held constant. The stoichiometry of the produced complex or complexes can be calculated based on where the curve breaks occur.
