Molar mass:-

→ The molar mass (symbol M, SI unit kg·mol−1) is defined as the mass per unit amount of substance of a given chemical entity. In keeping with the definition of the mole, the chemical entity in question should always be specified. Usually this will be a recognized atom, molecule or ion, but any collection, or indeed fragment, of such species may be specified. The molar mass of an element E may be obtained from tables such as those in this Encyclopaedia; usually these give the dimensionless 'Atomic Weight' Ar = M(E)/(10−3 kg·mol−1).
