Octane is a very large organic molecule made from eight atoms of carbon, and eighteen atoms of hydrogen. How many atoms are in an octane molecule?

Question

A
52

B
39

C
26

D
13

Answer 1

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
