Answer:
In chemistry, the term “stoichiometry” refers to the relationship between the quantities of reactants and products present before, during, and after chemical processes.
Stoichiometry is based on the law of conservation of mass, which states that the total mass of the reactants equals the total mass of the products.
This leads to the realization that the relationships between the quantities of reactants and products are typically expressed as a ratio of positive integers, which is the basis of stoichiometry. If the amounts of the individual reactants are known, then it is possible to determine the amount of the final product.
