It saves time.
It reduces errors.
And it makes chemistry much easier to understand.
Whether you are a student doing homework or someone working in a lab, this tool helps you get accurate numbers fast.
Enter Your Values Above
Just type in the known values, and the calculator will do the math for you. You’ll get clear results right away without long formulas or complex steps.
How to Use This Reaction Stoichiometry Calculator
Follow these simple steps:
- Enter the balanced chemical equation
- Type the known amount (mass or moles)
- Choose the substance you know
- Select the substance you want to find
- Click the calculate button
That’s it. The calculator will instantly show the result.
No manual conversions.
No long calculations.
How the Calculation Works (Simple Explanation)
Every balanced chemical reaction shows a ratio between substances. These numbers tell us how many moles react or are produced.
The calculator uses these steps:
- Convert the known value to moles (if it’s in grams)
- Use the mole ratio from the balanced equation
- Convert back to grams if needed
Easy Example
Reaction:
2H₂ + O₂ → 2H₂O
This means:
- 2 moles of hydrogen react with
- 1 mole of oxygen to produce
- 2 moles of water
If you start with 4 moles of Hâ‚‚, the ratio tells us you will get 4 moles of Hâ‚‚O.
The calculator does this instantly for you, even with large numbers or complex reactions.

Frequently Asked Questions (FAQs)
What is reaction stoichiometry?
It is the study of how much of each substance reacts or is produced in a chemical reaction.
Do I need a balanced equation?
Yes. The mole ratios come from the balanced equation. If it’s not balanced, the results will be wrong.
Can I enter grams instead of moles?
Yes. The calculator converts grams to moles automatically using molar mass.
What if I enter the wrong substance?
You can simply change the selected substance and calculate again. It updates instantly.
Is this calculator good for school exams?
It’s great for learning and checking work, but always practice solving problems by hand too so you understand the steps.
