A titration analysis was done to determine the arsenic acid (H3AsO4) content of an impure sample. The titrant used is a 0.454 M NaOH solution. To prepare the analyte for titration, a 0.3000 g impure arsenic acid sample was dissolved in 25.00 mL water. This solution was then titrated with the NaOH standard. Question: Calculate the molarity of the 25.00 mL arsenic acid solution if the initial volume of the titrant in the burette is 44.32 mL, and the final volume at endpoint is 32.74 mL.
