Molecular Weight Calculator

This free online Molecular Weight Calculator helps you find the molar mass of any compound by simply entering its molecular formula. Designed for chemistry and biochemistry students, researchers, and educators, it accurately parses formulas like H2O, NaCl, or (NH4)2SO4 and returns the molecular weight in grams per mole (g/mol).

How to Use

  • Enter the molecular or chemical formula in the input box. Example: C6H12O6 or CH3COOH
  • Click on the "Calculate" button
  • The tool will display the calculated molecular weight based on the atomic masses of elements

Features

  • Supports nested groups using parentheses (e.g. (NH4)2SO4)
  • Real-time validation and instant result display
  • Handles most common elements in the periodic table
  • Error handling for unknown or invalid formulas
  • Clean, responsive design for mobile and desktop

Who Can Use This Tool

  • Students studying organic or inorganic chemistry
  • Biochemistry researchers calculating compound weights
  • Educators and teachers needing quick molar mass reference
  • Anyone interested in chemical formula interpretation
