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.

Beryllium sulfate normally encountered as the tetrahydrate, [Be(H 2 O) 4]SO 4 is a white crystalline solid. It was first isolated in 1815 by Jons Jakob Berzelius. [4] Beryllium sulfate may be prepared by treating an aqueous solution of many beryllium salts with sulfuric acid, followed by evaporation of the solution and crystallization.
The straw-colored adduct Be(NO 3) 2 (N 2 O 4) forms upon treatment of beryllium chloride with dinitrogen tetroxide: . BeCl 2 + 3 N 2 O 4 → Be(NO 3) 2 (N 2 O 4) + 2 NOCl. Upon heating, this adduct loses N 2 O 4 and produces colorless Be(NO 3) 2.
