To determine the total number of atoms in one molecule of octane, we simply need to add the number of carbon (C) atoms and the number of hydrogen (H) atoms together.
Octane has:
- 8 carbon atoms
- 18 hydrogen atoms
Total number of atoms = Number of carbon atoms + Number of hydrogen atoms Total number of atoms = 8 + 18 = 26
Therefore, the answer is:
C 26
