Strong Acid Strong Base Titrations

Q. A strontium hydroxide solution is prepared by dissolving 10.35 g of Sr(OH)2 in water to make 53.00 mL of solution. What is the molarity of this solution? Express your answer to four significant figures and include the appropriate units. Next the strontium hydroxide solution prepared in part (a) is used to titrate a nitric acid solution of unknown concentration. Write a balanced chemical equation to represent the reaction between strontium hydroxide and nitric acid solutions. If a 23.9 mL of the strontium hydroxide solution was needed to neutralize a 31.5 mL aliquot of the nitric acid solution, what is the concentration (molarity) of the acid? Express your answer to three significant figures and include the appropriate units.
