    Answer:

    3.01 × 10^24 atoms of vitamin D

    Explanation:

    The number of atoms, molecules or ions present in a substance is given by the Avogadro’s number which is 6.02 × 10^23.

    Hence;

    1 molecule of vitamin D contains 6.02 ×10^23 atoms

    5 molecules of vitamin D contains 5 × 6.02 ×10^23/1

    = 3.01 × 10^24 atoms of vitamin D
