Formula Used in the Calculator
The calculator uses a simple stoichiometric formula:
Moles to Moles Formula:
Unknown Moles = (Known Moles × Unknown Coefficient) ÷ Known Coefficient
Conversion Factor:
Conversion Factor = Unknown Coefficient ÷ Known Coefficient
Stoichiometric Ratio:
Known Coefficient : Unknown Coefficient
Example Calculations
Example 1: Simple Ratio
- Known Moles = 2 mol
- Known Coefficient = 1
- Unknown Coefficient = 2
Calculation:
Unknown Moles = (2 × 2) ÷ 1 = 4 mol
Conversion Factor = 2 ÷ 1 = 2
Ratio = 1:2
Example 2: Equal Coefficients
- Known Moles = 5 mol
- Known Coefficient = 1
- Unknown Coefficient = 1
Calculation:
Unknown Moles = (5 × 1) ÷ 1 = 5 mol
Conversion Factor = 1
Ratio = 1:1
Example 3: Real Chemical Reaction
Consider the balanced equation:
2H₂ + O₂ → 2H₂O
If you have 6 moles of hydrogen (H₂), how many moles of water (H₂O) will form?
- Known Coefficient (H₂) = 2
- Unknown Coefficient (H₂O) = 2
Calculation:
Unknown Moles = (6 × 2) ÷ 2 = 6 mol
Key Features of This Tool
