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.
Molar mass: 212.996 g/mol (anhydrous) 375.134 g/mol (nonahydrate) ... It is, however, much less often encountered than aluminium chloride and aluminium sulfate ...
Overall, the Earth is about 1.59% aluminium by mass (seventh in abundance by mass). [64] Aluminium occurs in greater proportion in the Earth's crust than in the universe at large. This is because aluminium easily forms the oxide and becomes bound into rocks and stays in the Earth's crust, while less reactive metals sink to the core. [63]
A number of aluminium-containing raw materials can be used, including aluminium metal, alumina trihydrate, aluminium chloride, aluminium sulfate and combinations of these. The products can contain byproduct salts, such as sodium/calcium/magnesium chloride or sulfate. [12]

Copper(II) chloride, also known as cupric chloride, is an inorganic compound with the chemical formula Cu Cl 2. The monoclinic yellowish-brown anhydrous form slowly absorbs moisture to form the orthorhombic blue-green dihydrate CuCl 2 ·2H 2 O, with two water molecules of hydration. It is industrially produced for use as a co-catalyst in the ...
