How many oxygen atoms are there in one molecule of ethyl alcohol?

Ethyl alcohol (ethanol) has the chemical formula ${\text{C}}_2{\text{H}}_5\text{OH}$.Counting the individual atoms in one molecule of ethyl alcohol:Carbon ($\text{C}$) atoms = $2$ Hydrogen ($\text{H}$) atoms = $5+1=6$ Oxygen ($\text{O}$) atom = $1$ Therefore, there is exactly $1$ oxygen atom in a molecule of ethyl alcohol.
