Answer:
4 moles of H2SO4 are required
Explanation:
The reaction of H2SO4 with NaOH is:
H2SO4 + 2 NaOH → 2H2O + Na2SO4
That means, 2 moles of sulfuric acid reacts per mole of NaOH.
The moles of NaOH in 4L of a 2N NaOH are:
2N NaOH = 2 M = 2 moles of NaOH per liter.
4 liters are:
4L * (2 moles NaOH / L) = 8 moles NaOH.
That means you need to add:
8 moles NaOH * (1 mole H2SO4 / 2 moles NaOH) =
