Definitions of molecular mass, molecular weight, molar mass and molar weight

Molecular mass (molecular weight) is the mass of one molecule of a substance and 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 and is expressed in g/mol.Weights of atoms and isotopes are from NIST article.Related: Molecular weights of amino acidsmolecular weights calculated today Please let us know how we can improve this web app.
