Molar Mass Calculator

• Free online molar mass calculator that parses chemical formulas and computes molar mass
• Enter a chemical formula (e.g. H₂SO₄, C₆H₁₂O₆) and it is broken down automatically
• It shows the molar mass along with each element's count, atomic mass, subtotal, and mass percentage
• Perfect for chemistry students, lab work, and scientific research

1. Open the tool page — no installation needed
2. Type a chemical formula in the input box, or click an example (H₂O, CO₂, NaCl…) to fill it in instantly
3. Results update as you type (or click "Calculate"); review the molar mass and element breakdown, then use "Copy" to export or "Reset" to clear

• This tool is completely free and requires no sign-up
• All parsing and calculation run locally in your browser — your data never leaves your device
