Aluminium Chloride Hexahydrate Molecular Weight

Aluminium chloride hexahydrate is a chemical compound with the formula AlCl3·6H2O. It is a hydrated form of aluminium chloride, which means that it contains water molecules in its crystal lattice structure.

To calculate the molecular weight of aluminium chloride hexahydrate, we need to add up the atomic weights of each element present in the compound and multiply them by their respective number of atoms. The atomic weight of aluminium (Al) is 26.98 g/mol, chlorine (Cl) is 35.45 g/mol, and hydrogen (H) is 1.01 g/mol. The subscripts in the formula indicate the number of atoms of each element in the compound.

So, for aluminium chloride hexahydrate, we have:

Al: 1 atom x 26.98 g/mol = 26.98 g/mol

Cl: 3 atoms x 35.45 g/mol = 106.35 g/mol

H: 12 atoms x 1.01 g/mol = 12.12 g/mol

O: 6 atoms x 16.00 g/mol = 96.00 g/mol

Adding these values together gives us the molecular weight of aluminium chloride hexahydrate:

26.98 g/mol + 106.35 g/mol + 12.12 g/mol + 96.00 g/mol = 241.45 g/mol

Therefore, the molecular weight of aluminium chloride hexahydrate is 241.45 g/mol.
