4. Calculate the mass of Oxalic acid (H2C2O4*2H2O) required to neutralize 20.0 ml of 0.10 M NaOH solution using the balanced chemical equation for this reaction. 5. A 0.120 g sample of pure oxalic acid (H2C2O2*2H2O) was dissolved in water and neutralized with 21.0 ml of NaOH. Calculate the molarity of NaOH. Do not use scientific notation, but do use the proper number of significant digits and units.
A sample of oxalic acid (a diprotic acid of the formula H2C2O4) is dissolved in enough water to make 1.00 L of solution. A 100.0 mL sample of this solution is titrated with a solution of sodium hydroxide of concentration 0.750 M and requires 20.0 mL of sodium hydroxide to reach the end point. Calculate the mass of the original oxalic acid sample.
Calculate the amount of oxalic acid required to prepare 250 ml of 0.5 N solution?

Determine the concentration of H3O+ in a 0.064 M solution of oxalic acid, H2C2O4.H2C2O4(aq)+H2O(l) ⇌ H3O+(aq)+HC2O−4(aq) Ka1=0.054HC2O−4(aq)+H2O(l) ⇌ H3O+(aq)+C2O2−4(aq) Ka2=5.4×10−5
94.20 mL of 0.800 M potassium hydroxide reacts with 125.0 mL of a solution containing oxalic acid, H2C2O4, which is a diprotic species. What is the concentration of the acid solution?
The pH of a 0.20-M solution of oxalic acid (H2C2O4) is measured to be 1.10. Use this information to determine a value of Ka for oxalic acid. H2C2O4(aq) + H2O(l) HC2O4-(aq) + H3O+(aq) Ka =
A solution is prepared by dissolving 0.5892 g oxalic acid (H2C2O4) in enough water to make 100.0 mL of solution. A 10.00-mL aliquot (portion) of this solution is then diluted to a final volume of 250.0 mL. What is the final molarity of the diluted oxalic acid solution? I do not know if the answer of 0.00187 or 1.87 x 10^ -3 is correct. It is incorrect in my perspective, so i do not expect that answer, if you think...
