Avogadro's number is used to determine the small entity like the atoms and the molecules. 5.5 moles of magnesium hydroxide contain 3.31 × 10²⁴ molecules.
Molecules are the small entity that makes up the compound. It is made up of similar or different atoms.
If 1 mole of magnesium hydroxide = 6.02 ×10²³ molecules
Then 5.5 moles = 33.11 × 10²³ molecules.
Therefore, 3.31 × 10²⁴ molecules of magnesium hydroxide are present in 5.5 moles.
