Their goal was to neutralize 0.50 mol NaOH. How many moles of H2SO4 are needed to complete the neutralization?

Question

I do not understand how to solve this question and my EOC is thursday... this is due tonight!!! please help quickly 

Answer 1

Sodium hydroxide, a base, reacts with sulfuric acid to form sodium sulfate (complete neutralization) and water.  If you write the balanced equation, you will see that 2 moles of sodium hydroxide react with 1 mole of sulfuric acid to form 1 mole of sodium sulfate and 2 moles of water.  Therefore it would take .25 moles of sulfuric acid to react with .5 moles of sodium hydroxide.
