실제 예시

Example: With Moles of A = 2, Coefficient of A = 2, Coefficient of B = 3, the Stoichiometry Calculator gives Moles B: 3.

자주 묻는 질문

Why do I need a balanced equation first?

The mole-ratio conversion only works with the correct stoichiometric coefficients from a properly balanced chemical equation — unbalanced coefficients give wrong results.

Can I convert directly from mass instead of moles?

Convert mass to moles first (moles = mass / molar mass), then apply the mole ratio, then convert back to mass if needed.

What inputs does the Stoichiometry Calculator need?

You'll need to provide: Moles of A, Coefficient of A, Coefficient of B. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Stoichiometry Calculator?

The Stoichiometry Calculator applies the formula exactly as calculated — Mole ratio conversion: moles of B = moles of A × (coefficient of B / coefficient of A), using the balanced equation's stoichiometric coefficients. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Stoichiometry Calculator free to use?

Yes, the Stoichiometry Calculator is completely free, requires no signup, and runs instantly in your browser.
