What is Stoichiometry?
Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. It involves calculating the amounts of substances involved in a reaction, based on the balanced chemical equation. This includes mole-to-mole ratios, mass-to-mass conversions, and volume-to-volume relationships. Stoichiometry is fundamental for understanding how chemical reactions proceed and for predicting the outcomes of experiments. It relies heavily on concepts like molar masses, limiting reagents, and reaction stoichiometry to solve problems. By applying these principles, chemists can determine the theoretical yields of products, optimize reactions, and analyze the efficiency of processes. Stoichiometry is essential in fields like chemistry, engineering, and pharmacy, where precise calculations are critical for success.
