Question

Barium Chloride crystals contain 14.8% water of crystallization. find the number of molecules of water of crystallization per molecule​

Answer 1

Answer:

BaCl2. n H2O

Ba atomic mass=137

Cl atomic mass=35.5

molecular mass of water = 18

14.8% water means

14.8g of water in 100 g of BaCl2. n H2O

n x18 g water will be there in [137+71+n(18)]g of BaCl2. n H2O

1800xn = 14.8[208+n18]

1800n-266.4n=3078.4

1533.6n =3078.4

n= 2.0073

we can take n=2
