Question

How many sulfur (S) atoms in copper (II) sulfate pentahydrates?

Answer 1

Answer: In copper (II) sulfate pentahydrate, only 1 sulfur atom is present.

Step-by-step explanation:

The chemical formula of the copper (II) sulfate pentahydrate is
`CuSO_4.5H_2O`

In the given chemical formula:

Number of copper atoms = 1

Number of sulfur atoms = 1

Number of oxygen atoms = 9

Number of hydrogen atoms = 10

Hence, in copper (II) sulfate pentahydrate, only 1 sulfur atom is present.
