The balanced equation for the reaction is
2KOH + H₂SO₄  → K₂SO₄ + 2H₂O

The stoichiometric ratio between KOH and H₂SO₄ is 2 : 1

The moles of Sulfuric acid = 1.5 mol

moles of KOH / moles of H₂SO₄= 2 / 1
  moles of KOH / 1.5 mol            =  2
         moles of KOH                   =  2 x 1.5 mol = 3.0 mol

Hence, 3.0 moles of KOH are needed to neutralize the given H₂SO₄ acid
