Stoichiometry Calculator: Simple and Effective

What is Stoichiometry?

Stoichiometry is the calculation of quantities in chemical reactions. It allows you to determine how much product will form from given amounts of reactants, or how much reactant is needed to produce a desired amount of product. This calculator helps you perform these calculations quickly and accurately.

How to Use This Calculator

  1. Enter a balanced chemical equation using standard notation (e.g., 2H2 + O2 = 2H2O)
  2. Click "Parse Equation" to analyze the equation
  3. Select your known compound and enter its amount in grams
  4. Select the target compound you want to calculate
  5. Click "Calculate" to see the result

Enter Chemical Equation

Example equations you can try:

  • • 2H2 + O2 = 2H2O (Water formation)
  • • CH4 + 2O2 = CO2 + 2H2O (Methane combustion)
  • • 2Al + 3Cl2 = 2AlCl3 (Aluminum chloride formation)
  • • N2 + 3H2 = 2NH3 (Ammonia synthesis)

Understanding the Results

The calculator uses the following steps:

  1. Molar Mass Calculation: Determines the mass of one mole of each compound
  2. Mole Conversion: Converts the known mass to moles using molar mass
  3. Stoichiometric Ratio: Uses coefficients from the balanced equation to relate compounds
  4. Target Calculation: Converts moles of target compound back to grams

Introduction

This stoichiometry calculator helps you solve chemical reaction problems. It computes the mass of reactants or products using a balanced equation. You get quick and accurate answers.

What is Stoichiometry?

Stoichiometry deals with the amounts of chemicals in reactions. It shows the quantities needed to form compounds. This calculator turns chemical equations into easy numbers.

How to Use This Tool

Step 1: Enter Your Chemical Equation

Type your balanced equation in the box. Use standard chemical notation. For example, try 2H2 + O2 = 2H2O.

Step 2: Parse the Equation

Click the "Parse Equation" button. The tool will split the equation into parts and show each compound with its molar mass.

Step 3: Input Known Values

Select a known compound from the dropdown. Enter its mass in grams. Then, choose the compound you want to calculate.

Step 4: Calculate the Result

Click the "Calculate" button. The calculator converts grams to moles, applies the chemical ratios, and converts the moles back to grams. The final result appears on your screen.

Understanding the Input Fields

The chemical equation field accepts formulas like 2H2 + O2 = 2H2O.

The known compound dropdown shows all compounds from your entered equation.

The amount field is where you put the mass in grams.

The target compound dropdown lets you choose which compound you want to compute.

Interpreting the Output

The result shows the balanced equation and each compound's molar mass. It walks you through the steps of converting grams to moles and back. Read the steps to follow the calculation process.

Limitations and Special Notes

You must enter a balanced chemical equation. The calculator works best with basic reactions. It may not support very intricate formulas. Use standard notation for best results.
