How many moles of h2so4 are needed to completely neutralize 0.0164 mol koh

0.0082 moles of will be needed to neutralize the 0.0164 KOH.

Explanation:

2 moles of Potassium hydroxide neutralizes 1 mole of sulfuric acid.

Then 0.0164 moles of potassium hydroxide will neutralize of sulfuric acid that is 0.0082 moles.

0.0082 moles of will be needed to neutralize the 0.0164 KOH.
