Finding molarity of an oxalic acid given M and mls
You will be standardizing a .8 M NaOH solution using oxalic acid di-hydrate. You want to use about 15 mls per titration of NaOH. What should the molarity of your oxalic acid be?
Oxalic acid, H2C204, is used in the restoration of old wood. What is the molarity of oxalic acid if 29.78 mL of 0.538 M NaOH is required to titrate a 14.75 mL of an oxalic acid solution given the following reaction? (3 decimal places, fill in the number ONLY!) H2C2O4 (aq) + 2 NaOH (aq) → Na2C204 (aq) + 2 H20 (1)

You titrated a 22.00 mL solution of 0.0300 M oxalic acid with
freshly prepared solution of KMnO4. If it took 48.99 mL of this
solution, what is the molarity of the KMnO4?
0.022 L of 0.300 M oxalic acid
(0.022)(0.03) = 0.00066 mol oxalic acid
0.0006 mol oxalic acid x (2 mol KMnO4)/(5 mol oxalic acid)=
0.000264 mol KMnO4
0.000264 mol/0.04899 L = 0.05388855 M KMnO4
= 0.005388 M KMnO4
where did I go wrong?

molarity question What is the mass of oxalic acid, that is required to make 500ml of a 0.0500M solution? (M.WT = 90g/mol)
Suppose a 0.19M aqueous solution of oxalic acid (H2C2O4) is prepared. Calculate the equilibrium molarity of C2O4−2. You'll find information on the properties of oxalic acid in the ALEKS Data resource. Round your answer to 2 significant digits. pKa1=1.25 pKa2=3.81
3. A potassium hydroxide solution was standardized against the solid acid, oxalic acid dihydrate. The volume of the potassium hydroxide solution required to neutralize 0.317 grams of oxalic acid dihydrate was 48.82 milliliters. Calculate the molarity of potassium hydroxide solution. 4. The molarity of phosphoric acid in a popular cola is to be determined. A 355 mL sample of the cola is O 103 M potassium hydroxide solution. Calculate the molarity of phosphoric acid in the cola.
