A chemistry student needs to standardize a fresh solution of sodium hydroxide. He carefully weighs out 55 , mg of oxalic acid ( H2C2O4 ), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250. mL of distilied water. The student then titrates the oxalie acid solution with his sodium hydroxide solution. When the titration reaches the equivalence point, the student finds he has used 22.8mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 2 significant digits
