A chemistry student weighs out 0.0391g of phosphoric acid H3PO4 , a triprotic acid, into a 250.mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.1400M NaOH solution. Calculate the volume (in mL) of NaOH solution the student will need to add to reach the final equivalence point. Round your answer to 3 significant digits.
