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 H ₂O = 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 %
