What is the formula and name of a hydrate that is 85.3% barium chloride and 14.7% water

                                            BaCl₂.2H₂O

                                Barium Chloride Dihydrate

Proof:
                    Molecular Mass of BaCl₂  =  208.23 g/mol

                    Molecular Mass of 2 moles of H₂O  =  36 g/mol

                    Total Mass of BaCl₂.2H₂O  =  244.23 g/mol

%age of BaCl₂:

                      = 208.23 / 244.23 × 100  =  85.25 %  ≈  85.3 %

%age of H₂O:

                      = 36 / 244.23 × 100  =  14.74 %  ≈ 14.7 %
