A chemistry student weighs out
0.445g
of citric acid
H3C6H5O7
, a triprotic acid, into a
250.mL
volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with
0.0500M

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.
