A chemist needs to determine the concentration of a solution of nitric acid HNO3, She puts 865mL of the acid in a flask along with a few drops of indicator. She then slowly adds 0.600M Ba(OH)2 to the flask until the solution turns pink, indicating the equivalence point of the titration. She notes that 305mL Ba(OH)2 of was needed to reach the equivalence point.
How many moles of Ba(OH)2 are present in 305mL of 0.600 M Ba(OH)2
