There are three different types of atoms in acetic acid: carbon (C), hydrogen (H), and oxygen (O).
There are four hydrogen atoms in one molecule of acetic acid.
If a coefficient (big 2 in this case) is added in front of the formula, it indicates that you have two molecules of acetic acid. It does not change the number of atoms within a molecule; it simply multiplies the entire compound by the coefficient. So, in this case, you would have 2 molecules of C2H4O2.
