Semenov [28]

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

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.
