Online Chemistry Molar Mass Calculator
Instantly find the molar mass (or molecular weight) of any chemical compound. Our free online tool is essential for chemistry students, teachers, and researchers across India, simplifying complex calculations for lab work and study.
Chemical Formula
Enter a valid chemical formula (e.g., C6H12O6, Ca(OH)2).
Note on Atomic Masses
This calculator uses standard atomic weights as provided by IUPAC. The values are rounded for general-purpose calculations.
How to Use
- Enter Formula: Type the chemical formula into the input field (e.g., C6H12O6).
- Use Correct Case: Ensure elements are correctly cased (e.g., 'H' for Hydrogen, not 'h').
- Use Parentheses: Use parentheses for polyatomic ions (e.g., Ca(OH)2).
- Calculate: Click the "Calculate" button to see the molar mass and a detailed breakdown.
- Reset: Use "Reset" to clear the fields for a new calculation.
Example Calculation
Let's calculate the molar mass of Sulfuric Acid (H₂SO₄):
- Hydrogen (H): 2 atoms × 1.008 g/mol = 2.016 g/mol
- Sulfur (S): 1 atom × 32.06 g/mol = 32.06 g/mol
- Oxygen (O): 4 atoms × 15.999 g/mol = 63.996 g/mol
- Total Molar Mass: 98.072 g/mol
