Stoichiometry Calculator
Calculate reactant quantities and product yields for chemical reactions
Introduction
Stoichiometry is the quantitative study of reactants and products in chemical reactions. It uses the law of conservation of mass to calculate how much of each reactant is needed and how much product will be formed.
This calculator helps you determine limiting reagents, theoretical yields, and excess amounts for chemical reactions, essential for laboratory work and industrial processes.

Frequently Asked Questions
What is the limiting reagent?
The limiting reagent is the reactant that runs out first in a chemical reaction, limiting the amount of product that can be formed. It determines the theoretical maximum yield of the reaction.
What is theoretical yield?
Theoretical yield is the maximum amount of product that can be formed from the limiting reagent, assuming 100% reaction efficiency and no side reactions.
How do stoichiometric coefficients work?
Stoichiometric coefficients represent the molar ratios in which reactants combine and products are formed. They ensure the law of conservation of mass is satisfied in balanced chemical equations.
