Answer: 4 moles of Na are needed to produce 4 moles of NaCl

Explanation:

The balanced chemical equation is :

[tex]2Na+Cl_2\rightarrow 2NaCl[/tex]

According to stoichiometry :

2 moles of [tex]NaCl[/tex] are formed from = 2 moles of [tex]Na[/tex]

Thus 4 moles of [tex]NaCl[/tex] will be formed from = [tex]\frac{2}{2}\times 4=4moles[/tex]  of [tex]Na[/tex]

Thus 4 moles of Na are needed to produce 4 moles of NaCl
