In a titration, 15.5 g of oxalic acid was dissolved in a flask and neutralized with 31.2 mL of NaOH. Determine the molarity of the NaOH. Hint: Primary standards (like oxalic acid, here) incude water in their formula. As a result, they do not absorb atmospheric water. Oxalic acid has the chemcial formula: H2C2O4⋅2H2O (so be sure to include the 2 extra water molecules).
