Mole Ratio Calculator

Summary

Enter a balanced chemical equation and a known quantity to calculate the mole ratios and amounts of all reactants and products.

How it works

1. Enter the name and stoichiometric coefficient for each reactant and product.
2. Select which compound you already know the mole quantity for.
3. Enter the known mole amount in the input field.
4. Click Calculate to see the mole ratio table for all compounds.
5. Read off the moles for each substance or copy the results.

Use cases

• Determine how many moles of product form from a given amount of reactant.
• Find the theoretical yield for a chemical synthesis.
• Scale a reaction up or down while maintaining correct stoichiometry.
• Verify stoichiometric ratios in a balanced equation before running an experiment.
• Solve high school and university chemistry stoichiometry problems.
• Quickly compute limiting reagent relationships in multi-step reactions.
