In an acid-base titration, the neutralization of 20.00 mL of a solution of KOH (potassium hydroxide) of unknown concentration required the addition of 28.60 mL of 0.1042 M HNO3 (nitric acid). Calculate the molarity of the potassium hydroxide solution. Place your answer in the box. Express your answer using only a number or numbers without text. Report your result in decimal notation and to the proper number of significant figures. All numbers are measured.

A chemist needs to determine the concentration of a solution of nitric acid, HNO3. She puts 875 mLof the acid in a flask along with a few drops of indicator. She then slowly adds 0.200 MBa(OH)2 to the flask until the solution turns pink, indicating the equivalence point of the titration. She notes that 145 mL of Ba(OH)2 was needed to reach the equivalence point. Solution map In this titration, the concentration of base is known and can be used...
