.00160 moles bacl2

.0096 moles h2o

what is the hydrate # ?

number of hydrates (H₂O ) = 6

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
