* CO₂ is a molecule: It's made up of one carbon atom (C) and two oxygen atoms (O).
* 6CO₂ means six molecules: The "6" in front of the formula indicates that we have six of these CO₂ molecules.
Calculations:
* Atoms per molecule: 1 carbon atom + 2 oxygen atoms = 3 atoms per CO₂ molecule.
* Total atoms: 3 atoms per molecule * 6 molecules = 18 atoms
Therefore, there are 18 atoms in 6CO₂.
