Stoichiometric Ratio: Uses direct mole ratio

Step 5: Click “Calculate”

The calculator will display:

Target moles
Conversion factor
Mole ratio

Step 6: Reset if Needed

Click reset to clear inputs and start a new calculation.

Formulas Used in the Calculator

Forward Reaction:

Target Moles = (Given Moles × Target Coefficient) ÷ Given Coefficient

Reverse Reaction:

Target Moles = (Given Moles × Given Coefficient) ÷ Target Coefficient

Conversion Factor:

Conversion Factor = Target Coefficient ÷ Given Coefficient

Mole Ratio:

Given Coefficient : Target Coefficient

Example Calculations

Example 1: Forward Reaction

Given Moles = 4 mol
Given Coefficient = 2
Target Coefficient = 3

Calculation:
Target Moles = (4 × 3) ÷ 2 = 6 mol
Conversion Factor = 3 ÷ 2 = 1.5
Mole Ratio = 2:3

Example 2: Reverse Reaction

Given Moles = 6 mol
Given Coefficient = 2
Target Coefficient = 3

Calculation:
Target Moles = (6 × 2) ÷ 3 = 4 mol
Conversion Factor = 2 ÷ 3 = 0.667
Mole Ratio = 3:2

Example 3: Real Reaction Scenario

Consider the balanced equation:

N₂ + 3H₂ → 2NH₃

If you have 3 moles of hydrogen (H₂), how many moles of ammonia (NH₃) are produced?

Given Coefficient (H₂) = 3
Target Coefficient (NH₃) = 2

Calculation:
Target Moles = (3 × 2) ÷ 3 = 2 mol
