A chemist needs to determine the concentration of a solution ofnitric acid, HNO3. She puts 815mL of the acid in a flask along witha few drops of indicator. She then slowly adds 0.600MBa(OH)2 to the flask until the solution turns pink, indicating theequivalence point of the titration. She notes that 215mL of Ba(OH)2was needed to reach the equivalence point.
How many moles of HNO3 are present if 0.129mol ofBa(OH)2 was needed to neutralize the acid solution?
