Hello, Arshi,
The balanced equation
H2SO4 + 2NaOH -> 2H2O + Na2SO4
tells us that we produce 2 moles of H2O for every 1 mole of Na2SO4 produced. We are told that 2.0 moles of sodium sulfate were made. That would mean we also had 4 moles of water, since 2 (moles H2O/molesNa2SO4).
That means 4 moles of H2O should have formed. To convert to grams H2O, multiply by it's molar mass (18g/mole). That equals 72 grams.

What happens if it is 3.0 moles instead of 2.0 moles10/28/21
