In chemistry molar mass is defined as:
In chemistry, the molar mass (M) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of said compound. The molar mass is a bulk, not molecular, property of a substance. The molar mass is an average of many instances of the … See more The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, Mu = 0.99999999965(30)×10 kg⋅mol .
