Stoichiometric calculations are used in chemistry to determine amounts of substances in a chemical reaction. The basic steps include: Write the balanced chemical equation for the reaction. Identify the known amounts of substances involved in the reaction. Convert known amounts to moles, if necessary. Use the stoichiometric ratio of the balanced equation to perform ratio calculations. Calculate the unknown amount of the desired substance. It is important to consider the limiting reagent, which determines the maximum amount of product formed in the reaction. Stoichiometric calculations are useful for determining the amount of reactants needed, predicting the amount of products formed, and solving problems related to quantities in chemical reactions.
