Molecular Weight Calculator
Calculate molar mass of any chemical compound — enter formula like H2O, NaCl, C6H12O6.
H₂O = 18.015 g/mol, NaCl = 58.443, Glucose (C₆H₁₂O₆) = 180.156, H₂SO₄ = 98.079, CO₂ = 44.01. Molar mass is essential for stoichiometry — calculating reactant and product quantities in chemical reactions.
