A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 294. mg of oxalic acid (H, C,0,), 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 140.7 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 3 significant digits. OM Ox10

A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 294. mg of oxalic
acid (H, C,04),
, 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 140.7 mL of sodium hydroxide solution.
