How to Use the Molar Conversion Calculator
Follow these simple steps:
Step 1: Enter Molecular Weight
Input the molecular weight of the substance (g/mol).
Step 2: Select Conversion Type
Choose the type of conversion you want to perform.
Step 3: Enter Input Value
Provide the required value (mass, moles, or molarity).
Step 4: Enter Volume (if needed)
For molarity-related calculations, input the volume in liters.
Step 5: Click “Calculate”
The tool will instantly display:
- Result value
- Unit (g, mol, or M)
- Formula used
Formulas Used in the Calculator
Here are the core formulas applied:
- Moles (n) = Mass (m) ÷ Molecular Weight (M)
- Mass (m) = Moles (n) × Molecular Weight (M)
- Mass = Molarity (M) × Volume (L) × Molecular Weight
- Molarity (M) = Mass ÷ (Molecular Weight × Volume)
Example Calculations
Example 1: Mass to Moles
Input:
Mass = 10 g
Molecular Weight = 50 g/mol
Calculation:
n = 10 ÷ 50 = 0.2 mol
Example 2: Moles to Mass
Input:
Moles = 2 mol
Molecular Weight = 18 g/mol
Calculation:
m = 2 × 18 = 36 g
Example 3: Molarity to Mass
Input:
Molarity = 1 M
Volume = 2 L
Molecular Weight = 58.5 g/mol
Calculation:
m = 1 × 2 × 58.5 = 117 g
Example 4: Mass to Molarity
Input:
Mass = 29 g
Molecular Weight = 58 g/mol
Volume = 1 L
Calculation:
M = 29 ÷ (58 × 1) = 0.5 M
