Which listed value is closest to the total number of atoms in one mole of methanol, CH₃OH?

Explanation

Methanol, CH₃OH, contains one carbon atom, four hydrogen atoms and one oxygen atom, for six atoms per molecule. One mole contains the Avogadro number of molecules, so it contains 6 × 6.02214076 × 10²³ atoms, approximately 3.61 × 10²⁴. The closest listed value is 3.6 × 10²⁴.
