A chemistry student needs to standardize a fresh solution of
sodium hydroxide. He carefully weighs out 433.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 oxalic acid solution with his sodium
hydroxide solution. When the titration reaches the equivalence
point, the student finds he has used 120.3 mL of sodium hydroxide
solution. Calculate the molarity of the student's sodium hydroxide
solution. Round your answer to 3 significant digits.
