0.408 g of an unknown triprotic acid are used to make a 100.00 mL solution. Then 25.00 mL of this solution is transferred to an Erlenmeyer flask and is titrated with 0.1125 M NaOH. The initial burette reading is 0.82 mL; when the titration endpoint is reached, the final burette reading is 37.62 mL. How many moles of triprotic acid are neutralized during the titration? Provide your answer in decimal form (e.g. 0.123) to the correct number of significant figures.
