Stoichiometry Calculator
Free, instant stoichiometry calculator with step-by-step solutions, transparent formulas, and verification.
Quick answer
Stoichiometry converts between mass and moles using a balanced chemical equation. The reactant with the smaller available mole-to-coefficient ratio limits the theoretical product yield.
Formula and calculation method
moles = mass / molar mass; product moles = limiting moles × (product coefficient / reactant coefficient); mass = moles × molar mass.
