Molar Mass Calculator: Compute Any Chemical Formula

Calculate the molar mass of any chemical compound with this comprehensive Molar Mass Calculator! Input a chemical formula (e.g., H₂O, CO₂, NaCl, or even complex ones like UO2) and get the molar mass in grams per mole. This tool supports all naturally occurring elements, making it ideal for chemistry students, educators, and professionals.

How It Works

Enter a chemical formula in the box below and click “Calculate.” The tool parses the formula and computes the molar mass using atomic masses for all 118 known elements, with results rounded to two decimal places.

Instructions

1. Enter a chemical formula (e.g., H2O for water, CO2 for carbon dioxide, NaCl for sodium chloride, or UO2 for uranium dioxide).
2. Click the "Calculate" button.
3. The molar mass will be displayed in grams per mole (g/mol).

Features

• Supports all 118 known chemical elements, from Hydrogen (H) to Oganesson (Og).
• Handles multi-character elements and subscripts (e.g., H2O means 2 hydrogen atoms and 1 oxygen atom).
• Displays errors for invalid formulas or unrecognized elements.
• Styled to integrate seamlessly with WordPress themes, offering a clean and responsive interface.

Limitations

• Requires proper capitalization (e.g., "Na" for sodium, not "na").
• Does not support complex formulas with parentheses (e.g., (NH4)2SO4).
• Atomic masses for some superheavy elements are approximate due to their instability.
