Answer 2

The correct answer is (D) They both have the same number of atoms.

The Explanation:

as we compare 1 mole of Mg with 1 mole iron so they have the same number of moles .

and when the number of atoms = number of moles * Avogadro's number

= 6.02 x 10^23

∴ both have the same number of atoms
