A sample of KHC2O4 weighing 0.5839 g is dissolved in 25 mL of water and an endpoint is reached when 31.99 mL of KOH has been added. Calculate the molarity of the KOH solution.

KHC2O4(aq) + KOH(aq) ¨ K2C2O4(aq) + H2O(l)

because the coefficents are all the same, i just assumed that KOH also had 0.5839 g, converted into mols, and divdied by the total volume. however, this answer was wrong...
