Molarity of student sodium hydroxide solution

Assignment Help Chemistry
Reference no: EM132651048

A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 76. mg of oxalic acid H2C2O4, a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250. mLof 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 123.5 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 2 significant digits.
