A chemistry student needs to standardize a fresh solution of sod!um hydroxide. She carefully weighs out 276. mg of oxalic acid (H,C,O, 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 118.6 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 3 significant digits.
