A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 17 mg of oxalic acid (H₂C₂O₄), 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 16.4 mL of sodium hydroxide solution.Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 2 significant digits.[Input Box for Molarity]Options to submit an answer or question are available.There are no graphs or diagrams included in the image.
