A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 115. 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 oxallc acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 76.4 ml of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution, Be sure your answer has the correct number of significant digits.
