A 36.0 mL sample of aqueous sulfuric acid was titrated with 0.250 M KOH(aq) until the acid-base indicator signaled that the solution was neutralized. The mixture was then carefully evaporated to dryness, the residue was dried in a drying oven. The residue was then weighed and a value of 861 mg was obtained for its mass. Calculate a value for the volume of the potassium hydroxide solution that was used in the titration from this data. Answer with correct units and significant figures.
