The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.

Zinc bromide (Zn Br 2) is an inorganic compound with the chemical formula Zn Br 2. It is a colourless salt that shares many properties with zinc chloride (ZnCl 2), namely a high solubility in water forming acidic solutions, and good solubility in organic solvents. It is hygroscopic and forms a dihydrate ZnBr 2 ·2H 2 O. [2]
