Step 2: Enter Molar Mass
Provide the molar mass (g/mol) of the substance.
Example:
- 58.5 g/mol (for NaCl)
Step 3: Enter Valency (n-factor)
Input the n-factor, which depends on the chemical reaction or compound behavior.
Example:
- 1 for NaCl
- 2 for CaCl₂
Step 4: Click Calculate
The tool instantly shows:
- Moles (mol)
- Equivalent (eq)
Step 5: View Results
The results appear in a clean format with formulas shown for better understanding.
Step 6: Copy or Share
You can copy or share the results directly for lab reports or study notes.
🧮 Practical Example 1: Chemistry Lab Experiment
Imagine you are working in a chemistry lab and need to calculate moles of sodium chloride (NaCl).
Given Data:
- Mass = 11.7 g
- Molar Mass = 58.5 g/mol
- n-factor = 1
Results:
- Moles = 11.7 ÷ 58.5 = 0.2 mol
- Equivalent = 0.2 × 1 = 0.2 eq
Use Case:
This helps in preparing solutions with correct molarity for experiments.
🧪 Practical Example 2: Acid-Base Titration
In titration experiments, equivalent calculations are very important.
Given Data:
- Mass of acid = 4.9 g
- Molar Mass = 49 g/mol (example acid)
- n-factor = 2
Results:
- Moles = 4.9 ÷ 49 = 0.1 mol
- Equivalent = 0.1 × 2 = 0.2 eq
Use Case:
This helps in determining how much acid is needed to neutralize a base accurately.
