To find the moles of oxalic acid, you need to use the given information and the equation:

H2C2O4 + 2NaOH ---> Na2C2O4 + 2H2O

First, let's calculate the moles of oxalic acid dihydrate (H2C2O4.2H2O):

Moles of oxalic acid dihydrate = 0.032 mole

Since oxalic acid dihydrate (H2C2O4.2H2O) has a molar mass of 126.07 g/mol, we can calculate the grams of oxalic acid dihydrate:

Grams of oxalic acid dihydrate = Moles of oxalic acid dihydrate x Molar mass
= 0.032 mole x 126.07 g/mol
= 4.03 g

Next, let's calculate the moles of oxalic acid:

Moles of oxalic acid = Grams of oxalic acid / Molar mass

The molar mass of oxalic acid (H2C2O4) is 90.04 g/mol. So,

Moles of oxalic acid = 4.03 g / 90.04 g/mol
= 0.045 mole

Therefore, the mole of oxalic acid is 0.045 mole.

To find the number of moles of oxalic acid in this equation, we need to use the balanced chemical equation and the given information.

The balanced chemical equation is:
H2C2O4 + 2NaOH → Na2C2O4 + 2H2O

From the equation, we can see that the ratio between oxalic acid (H2C2O4) and sodium oxalate (Na2C2O4) is 1:1. This means that for every mole of oxalic acid, we will have one mole of sodium oxalate.

Given:
Moles of oxalic acid dihydrate = 0.032 mole
Molarity of oxalic acid solution = 0.128 M
Initial volume of oxalic acid = 19.8 ml
Final volume of oxalic acid = 23.0 ml

First, let's find the number of moles of oxalic acid using the given molarity and volume.

Moles = Molarity x Volume
Moles = 0.128 M x (19.8 ml / 1000) L
Moles = 0.128 M x 0.0198 L
Moles = 0.00254 mole

The number of moles of oxalic acid in the solution is found to be 0.00254 mole.

Now, let's convert the moles of oxalic acid dihydrate to moles of oxalic acid. Since the mole ratio between oxalic acid and oxalic acid dihydrate is 1:1, the number of moles will be the same.

Therefore, the mole of oxalic acid is 0.032 mole.

In summary, the mole of oxalic acid is 0.032 mole.
