A solution of KOH is prepared by dissolving 2.00 g of KOH in water to a final volume of 250 ml of solution what volume of this solution will neutralize 20.0 ml of 0.115 mol/L sulfuric acid?
amount of KOH= 2.00g(1mol of KOH/ 56.01g)= 0.357 moles
concentration of KOH in water = amount of KOH/ volume of kOH= ( 0.357 mol/(25x10^-3)= 14 mol/ l

1. molar mass KOH is 56.1 for starters and
2.00/56.1 = 0.0357
M KOH = 0.0357/0.250 = 0.143 instead of your number of 14.

H2SO4 + 2KOH ==> K2SO4 + + 2H2O
mols H2SO4 = M x L = ?
Using the coefficients in the balanced equation, convert mols H2SO4 to mols KOH.
Then M KOH = mols KOH/L KOH. YOu know M KOH and mols KOH, solve for L KOH
