* The Formula: 2C2H6O represents two molecules of ethanol (ethyl alcohol).
* One Molecule: Each molecule of ethanol (C2H6O) contains 6 hydrogen atoms.
* Total Hydrogen Atoms: Since you have two molecules, the total number of hydrogen atoms is 6 atoms/molecule * 2 molecules = 12 hydrogen atoms.
Therefore, there are 12 hydrogen atoms in 2C2H6O.
