Question

BaCl2 · ____(H2O)

.00160 moles BaCl2

.0096 moles H2O

What is the hydrate # ? ______

Answer 1

number of hydrates (H₂O ) = 6

Step-by-step explanation:

Data Given:

moles of BaCl₂ = 0.0016

moles of H₂O = 0.0096

number of hydrates = ?

Solution:

As we have moles of BaCl₂ and H₂O water.

First find the simplest ratio of BaCl₂ and H₂O

Ratio BaCl₂ : H₂O

0.0016 : 0.0096

Now divide the ratio on smallest number to get simplest ratio

BaCl₂ : H₂O

0.0016 / 0.0016 : 0.0096 / 0.0016

1 : 6

So,

The ratio of BaCl₂ to water (H₂O) is 1 to 6. it means there are 6 water molecules are present.

The formula of hydrated Barium Chloride will be

BaCl₂. 6H₂O

So the number of hydrates will be 6
