Question

A chemist needs to determine the concentration of a solution of nitric acid, HNO3. She puts 905 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, indicating the equivalence point of the titration. She notes that 245 mL of Ba(OH)2 was needed to reach the equivalence point.

What is the concentration of HNO3 if 0.294 mol are present in 905 mL of the solution?
