⚖️ Molar Mass Calculator

Enter a chemical formula to calculate its molar mass. The calculator provides a detailed element‑by‑element breakdown.

How to Use

  1. Type a chemical formula into the input field (e.g., H2O, C6H12O6, H2SO4).
  2. Use capital letters for elements (e.g., Cl for chlorine, Na for sodium).
  3. The calculator will show the total molar mass and a breakdown per element.
  4. Try common molecules like Water, Methane, or Glucose.

What is Molar Mass?

The molar mass of a chemical compound is the mass of one mole of that substance, expressed in grams per mole (g·mol⁻¹). It is calculated by summing the atomic masses of all atoms in the molecular formula. For example, water (H₂O) has a molar mass of 18.015 g·mol⁻¹ — 2 × 1.008 (hydrogen) + 15.999 (oxygen). Molar mass is essential for stoichiometric calculations in chemistry.
