Answer: Option (b) is the correct answer.
Step-by-step explanation:
Since, the chemical formula of acetic acid is
. And, symbol which represents a carbon atom is C, hydrogen atom is represented by H and an oxygen atom is represented by O.
Therefore, as in a molecule of acetic acid there are total 2 carbon atoms, 4 hydrogen atoms and total 2 oxygen atoms.
Thus, we can conclude that there are 2 atoms of the element carbon (C) are in a molecule of acetic acid.
