What Is The Molecular Weight Of Aluminium Chloride Hexahydrate?

The molecular weight of aluminium chloride hexahydrate can be calculated by adding the atomic weights of all the atoms in one molecule of the compound.

Aluminium chloride hexahydrate has the chemical formula AlCl3·6H2O, which indicates that each molecule contains one aluminium ion (Al3+) and three chloride ions (Cl-) as well as six water molecules (H2O).

To calculate the molecular weight, we need to find the atomic weights of each element based on the periodic table. The atomic weight of aluminium is 26.98 g/mol, the atomic weight of chlorine is 35.45 g/mol, and the atomic weight of hydrogen and oxygen are 1.01 g/mol and 16.00 g/mol, respectively.

Therefore, the total molecular weight of aluminium chloride hexahydrate can be calculated as:

(1 x 26.98) + (3 x 35.45) + (12 x 1.01) + (6 x 16.00) = 241.43 g/mol

So, the molecular weight of aluminium chloride hexahydrate is approximately 241.43 grams per mole.
