Sodium hydroxide (NaOH) consists of one sodium (Na) atom, one oxygen (O) atom, and one hydrogen (H) atom.
Multiplying the chemical formula by 2, we get:
2 NaOH = 2 Na + 2 O + 2 H
Therefore, there are 2 sodium atoms, 2 oxygen atoms, and 2 hydrogen atoms in 2 NaOH.
In total, there are 2 + 2 + 2 = 6 atoms in 2 NaOH.
