Computing molecular weight (molecular mass)To calculate molecular weight of a chemical compound enter it"s formula, specify its isotope mass number after each element in square brackets.Examples of molecular weight computations: C<14>O<16>2, S<34>O<16>2.
Definitions of molecular mass, molecular weight, molar mass & molar weightMolecular mass (molecular weight) is the mass of one molecule of a substance & is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance & is expressed in g/mol.Weights of atoms and isotopes are from NIST article.Related: Molecular weights of amino acids
