Hello Dear User__________

Here is Your Answer...!!

____________________

Explanation:Answer:

Given formula of blue vitriol i.e. copper sulphate

We have to find tatal numbers of atoms here

CuSO₄.5H₂O

Total number of Cu atom = 1

Total number of S atom = 1

Total number of O atoms = 4+5=9

Total number of H atoms = 5 × 2 =10

Tatal numbers of atoms in CuSO₄.5H₂O = 1+1+9+10=21

So option B is correct.

Hope it is clear to you.
