Molecular weight or molecular mass is the mass of one mole of a substance. It is the measure of atomic weights of the atoms in a molecule. It is expressed in grams per mole. If the number of moles needed for a substance is given, then we use the molar mass concept to find the number of grams of the substance. Online Molecular Weight Calculator to calculate molar mass by providing the formula of the chemical elements.
