Understanding the Importance of Stoichiometry Questions and Answers PDF
What Is Stoichiometry?
Stoichiometry is a 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 reactions, typically expressed in moles, grams, molecules, or volume (for gases). Mastery of stoichiometry enables students to predict yields, determine limiting reactants, and understand reaction efficiencies.
