Example Calculation
Let’s understand how this tool works with a practical example:
Given Values:
- Molecular Weight (A): 18 (Water)
- Coefficient (B): 2
- Reactant Mole (C): 5 moles
- Volume (D): 10 liters
Step-by-Step Result:
1. Stoichiometric Ratio
B ÷ A = 2 ÷ 18 = 0.111
2. Required Mole
C × Ratio = 5 × 0.111 = 0.555 moles
3. Excess / Deficit
C − Required = 5 − 0.555 = 4.445 moles (Excess)
4. Final Concentration
Required ÷ Volume = 0.555 ÷ 10 = 0.0555 mol/L
Final Output:
- Stoichiometric Ratio: 0.111
- Required Mole: 0.555
- Excess/Deficit: 4.445
- Final Concentration: 0.056 mol/L
This shows how the calculator quickly determines whether you have excess reactant and what the final concentration will be.
