Answer: 2 moles of [tex]H_2O[/tex] will be formed.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} NaOH=\frac{80g}{40g/mol}=2moles[/tex]

The balanced chemical equation is:

[tex]H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O[/tex]

According to stoichiometry :

2 moles of [tex]NaOH[/tex] give = 2 moles of [tex]H_2O[/tex]

Thus 2 moles of [tex]NaOH[/tex] give =[tex]\frac{2}{2}\times 2=2moles[/tex] of [tex]H_2O[/tex]

Thus 2 moles of [tex]H_2O[/tex] will be formed.
