A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide
solution. He has a 0.1598 M standard sodium hydroxide solution. He takes a 25.00 mL sample of the original acid solution
and dilutes it to 250.0 mL. Then, he takes a 10.00 mL sample of the dilute acid solution and titrates it with the standard
solution. The endpoint was reached after the addition of 11.55 mL of the standard solution. What is the concentration of the
original sulfuric acid solution?
