Answer 2

Answer : The correct option is, 2

Explanation :

The given molecule is,
`Ni(OH)_2`. It is made up of 1 mole of nickel ion and 2 mole of hydroxide ion.

In the given molecule of nickel hydroxide :

The number of nickel atoms = 1

The number of oxygen atoms = 2

The number of hydrogen atoms = 2

Hence, the number of oxygen atoms present in one molecule of nickel hydroxide is, 2.
