A chemistry student weighs out 0.364 g of citric acid (H2CH20-), a triprotic acid, into a 250. mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.0600M NaOH solution.
Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Round your answer
to 3 significant digits.
