4 co₂
carbon dioxide
how many oxygen (o) atoms are in 4 co₂?
4 oxygen atoms
8 oxygen atoms
2 oxygen atoms
6 oxygen atoms

Explanation:

Step1: Analyze one $CO_2$ molecule

One $CO_2$ molecule has 2 oxygen atoms.

Step2: Calculate for 4 $CO_2$ molecules

Multiply the number of oxygen atoms in one $CO_2$ by 4. So, $4\times2 = 8$.

Answer:
