Answer: 7.2 moles of Na are required to make 2.4 moles of Fe.
Explanation:
The balanced chemical equation is:
[tex]6Na+Fe_2O_3\rightarrow 3Na_2O+2Fe[/tex]
According to stoichiometry:
2 moles of Fe are produced from = 6 moles of Na
Thus 2.4 moles of Fe are produced from = [tex]\frac{6}{2}\times 2.4=7.2[/tex] moles of Na.
Thus 7.2 moles of Na are required to make 2.4 moles of Fe.
