A chemistry student weighs out 0.184 g of phosphoric acid (H, PO a triprotic acid, into a 250. ml. volumetric flask and dilutes to the mark with water. He plans to titrate the acid with 0.1400M NAOH solution. Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Be sure your answer has the correct number of significant digits.
