Answer: There are $145 \times 10^{23}$ atoms in 24 moles of Fe.

Explanation:

According to the mole concept, 1 mole of a substance contains $6.022 \times 10^{23}$ atoms.

Therefore, atoms present in 24 moles of Fe are calculated as follows.

$24 mol \times 6.022 \times 10^{23} atoms/mol\\= 144.52 \times 10^{23} atoms\\or, 145 \times 10^{23} atoms$

Thus, we can conclude that there are $145 \times 10^{23}$ atoms in 24 moles of Fe.
