Reaction Mole Ratio Calculator
Find mole ratios in a balanced reaction.
About Reaction Mole Ratio Calculator
Stoichiometric ratios for Reaction Mole Ratio scale reactant amounts by the coefficient ratio in the balanced equation to find how much product forms. Balanced coefficients are the exact conversion factors between reactants and products.
Formula
Reaction Mole Ratio
Product moles = reactant moles x (product coefficient / reactant coefficient)
- coefficient
- The number in the balanced equation

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Reaction Mole Ratio calculated?
