Answer: There are 6 mole of oxygen present in 1 mole of \(Mg(ClO_{3})_{2}\).
Explanation:
The given formula of compound is \(Mg(ClO_{3})_{2}\). In this compound, there are 1 mole of magnesium, 2 mole of chlorine and \(3 \times 2 = 6\) mole of oxygen atom.
Therefore, we can conclude that the total number of moles of oxygen atoms present in 1 mole of \(Mg(ClO_{3})_{2}\) is 6 mole.
