Answer: The correct answer is six.
Step-by-step explanation:
The chemical name for the given chemical formula is methanol. This is an organic compound in which a covalent bond is present between hydrogen and carbon atom.
In a single mole of this compound, there are 3 different types of elements are present. The elements are carbon, hydrogen and oxygen.
In 1 mole of methanol, 1 mole of carbon atom, 4 moles of hydrogen atoms and 1 mole of oxygen atoms are present.
Thus, in total 6 atoms are present in 1 mole of methanol molecule.
