Molecular Weight Calculator
Enter a chemical formula (e.g. H2O, NaCl, Ca(OH)2, H2SO4) to calculate its molecular weight. Parentheses and coefficients are supported.
Common examples: H2O (water = 18.015), NaCl (table salt = 58.44), H2SO4 (sulfuric acid = 98.079), Ca(OH)2 (calcium hydroxide = 74.093)
