Stoichiometry is the study of the quantitative relationships between reactants and products in chemical reactions. It allows chemists to predict how much of each substance is needed or produced in a reaction based on balanced equations.
Enter a balanced chemical equation with coefficients. Select the known compound and enter its amount. Choose the compound you want to calculate and the desired unit. Click Calculate to get the result instantly.
Mole ratios from balanced equations show the relationship between reactants and products. The calculator uses these ratios to convert between different units (moles, grams, molecules) while maintaining the correct proportions.
For the reaction 2 H2 + O2 → 2 H2O, if you have 4 moles of H2, you can calculate that you need 2 moles of O2 and will produce 4 moles of H2O. The calculator handles these conversions automatically.
