Question

Barium chloride crystals contain 14.8% water of crystallization. Find the number of molecules of water of crystallization per molecule.

Answer 1

Barium chloride = BaCl₂. x H₂O

Ba + 2Cl + x[H₂ + O]

=137+ 35.5 + x [2+16]

=[208 + 18x] contains water = 14.8% water in BaCl₂. x H₂O

=[208 + 18 x] `14.8/100` = 18x

=[104 + 9x] 2148 =18000x

=[104 + 9x] 37 = 250x

=3848 + 333x = 2250x

1917x = 3848

x = 2 molecules of water
