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. read more

Mass of one mole molecules of any compound or element is known as molar mass. It is generally described as the sum of mass numbers of its constitutional atoms but written in grams. C = 12. O= 16. Hence for CO2, 12+16+16=32. 32 grams per mole. Additional info: Generally, Mass number of an atom is described in amu units (atomic mass unit). read more

›› More information on molar mass and molecular weight In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. read more
