Explanation:
Step 1:
Data obtained from the question
Number of mole of Fe = 3 moles
Number of atom =?
Step 2:
Determination of the number of atom.
From Avogadro's hypothesis, we understood that:
1 mole of Fe = 6.02×10²³ atoms
Therefore,
3 moles of Fe = 3 × 6.02×10²³ atoms
3 moles of Fe = 1.806×10²⁴ atoms
Thus, 3 moles of iron, Fe contains 1.806×10²⁴ atoms.
