Stan Taizing A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 45. mg of oxalic acid (H₂C₂04), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250. mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 87.9 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution.

A chemistry student needs to standardize a fresh solution of sodium
hydroxide. She carefully weighs out 45. mg of oxalic acid (H₂C₂O), a diprotic
acid that can be purchased inexpensively in high purity, and dissolves it in
250. mL of distilled water. The student then titrates the oxalic acid solution
with her sodium hydroxide solution. When the titration reaches the
equivalence point, the student finds she has used 87.9 mL of sodium
hydroxide solution.
