A solution containing an unknown concentration of HBr was titrated with 0.100 M KOH. 25.00 mL of the HBr solution was pipetted into a beaker. The HBr solution was then titrated with the 0.100 M KOH and 18.60 mL of KOH was added to reach the end point. Calculate the concentration of the HBr in the original solution
