NaOH + HSO -+ Which of the following is the number of moles of NaOH required to neutralize 1 mole of H2SO4 in the equation above?

If you wrote the equation right it should be obvious.

2NaOH + H2SO4 ==> Na2SO4 + 2H2O
2 mols NaOH neutralize 1 mol H2SO4.

To determine the number of moles of NaOH required to neutralize 1 mole of H2SO4, we need to look at the balanced chemical equation.

The given equation is:
NaOH + H2SO4 → Na2SO4 + H2O

From the equation, it can be observed that the stoichiometric ratio between NaOH and H2SO4 is 1:2. This means that one mole of NaOH reacts with two moles of H2SO4.

Therefore, to neutralize 1 mole of H2SO4, we need half a mole (0.5 moles) of NaOH.
