## Quick Answer

Calculate reactant and product yields. Enter reactant amount, molar masses, and balanced equation coefficients to compute moles and theoretical product grams.

## Definition

A stoichiometry calculator is an educational chemistry tool used to compute quantitative relationships between reactants and products in a balanced chemical reaction. Based on the law of conservation of mass, the tool converts the starting mass of a reactant into moles using its molar mass, applies the stoichiometric coefficient ratio between the reactant and product, and converts the resulting product moles back into mass in grams. Chemistry students and researchers use this calculator to find theoretical yields, analyze reaction proportions, and verify chemical equations.

## How to Use

1. **Input starting reactant** — Enter the starting reactant quantity and select either grams or moles.
2. **Enter molar masses** — Input the molar mass in grams per mole for both the reactant and product.
3. **Set equation coefficients** — Type the stoichiometric coefficients from the balanced chemical equation.
4. **Read product yield** — Review the calculated moles and theoretical grams of the resulting product.
