    Answer: There are 0.617 \times 10^{4} moles present in 3.72 \times 10^{27} atoms of iron.

    Explanation:

    According to the mole concept, there are 6.022 \times 10^{23} atoms present in one mole of a substance.

    Hence, moles present in 3.72 \times 10^{27} atoms are calculated as follows.

    Moles = \frac{3.72 \times 10^{27}}{6.022 \times 10^{23}}\\= 0.617 \times 10^{4} mol

    Thus, we can conclude that there are 0.617 \times 10^{4} moles present in 3.72 \times 10^{27} atoms of iron.
