6.022×10²³ molecules Oxygen

Explanation:

To get molecules, you will need Avogadro's number.

Avogadro's number: 6.022×10²³ molecules/mole

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
