Determining the volume of base needed to titrate a given mass of acid.

Extracted text: A chemistry student weighs out 0.155 g of lactic acid (HC,H,O,) into a 250. mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.2000M NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the equivalence point. Be sure your answer has the correct number of significant digits. O ml
