Suppose 0.09886 M KOH is titrated into 15.00 mL H2SO4 of unknown concentration until the equivalence point is reached. It takes a total volume of 29.25 mL KOH to neutralize the H2SO4.

How many moles of base were needed to reach the equivalence point? Express the answer to five significant figures.
