1. Identify the chemical formula:

* The formula is CH₃COOH, which represents acetic acid.

2. Count the oxygen atoms in one molecule:

* There are two oxygen atoms (O) in each molecule of acetic acid (CH₃COOH).

3. Multiply by the coefficient:

* The coefficient "6" in front of the formula indicates that there are six molecules of acetic acid.

* Multiply the number of oxygen atoms per molecule by the number of molecules: 2 oxygen atoms/molecule * 6 molecules = 12 oxygen atoms.

Therefore, there are 12 oxygen atoms in 6CH₃COOH.
