A chemist needs to determine the concentration of a solution of nitric acid, HNO3. She puts 835 mL of the acid in a flask along with a few drops of indicator. She then slowly adds 0.600 M Ba(OH)2 to the flask until the solution turns pink, indicatig the equilvalence point of the titration. She notes that 245 mL of Ba(OH)2 was needed to reach the equilvalence point.

In this titration, the concentration of base is known and can be used to calculate the unknown acid concentration:

concentration of base--> moles of base---> moles of acid----->concentration of acid

How many moles of Ba(OH)2 are present in 245 mL of 0.600 M Ba(OH)2?
