Answer 2

The total number of atoms represented by the compound CuSO4.5H2O are 21.

• CuSO₄·5H₂O is called hydrated copper sulfate or blue vitriol.
• It appears blue in color because of water of crystallization.
• The atoms present in CuSO₄·5H₂O are:

1. Copper (Cu) = 1 atom
2. Sulphur (S) = 1 atom
3. Oxygen (O)= 4 atoms in CuSO₄ and 5 atoms in 5 water molecules = 9 atoms
4. Hydrogen (H)= 10 atoms

• Total number of atoms= 1+1+9+10

          = 21 atoms
