**Titration of Citric Acid with Sodium Hydroxide**

A solution of citric acid \((H_3C_6H_5O_7)\) with a known concentration of \(0.200 \, M \, H_3C_6H_5O_7\) is titrated with a \(0.750 \, M \, NaOH\) solution. The goal is to determine how many milliliters of NaOH are required to reach the third equivalence point, starting with a volume of \(25.0 \, \text{mL} \, H_3C_6H_5O_7\). 

The balanced chemical equation for the reaction is:

\[ H_3C_6H_5O_7 + 3 \, \text{NaOH} \rightarrow \text{Na}_3C_6H_5O_7 + 3 \, \text{H}_2\text{O} \]

### Calculation Setup:

**Inputs and Controls:**
- **Starting amount:** Initial molarity and volume conditions.
- **Add Factor:** Includes numbers \(1, 3, 1000, 6.67, 7, 15.0, 20.0, 0.020, 2\) and equivalence/conversion factors like \(25.0, 11.25, 2.22\).
- **Answer and Reset:** Fields to input answers and reset calculations.

**Controls for Chemical Units:**
- \(g \, H_3C_6H_5O_7\)
- \(M \, H_3C_6H_5O_7\)
- \(mL \, NaOH\)
- \(L \, NaOH\)
- \(mol \, H_3C_6H_5O_7\)
- \(L \, H_3C_6H_5O_7\)

### Procedure:

1. **Determine the moles of citric acid** using the molarity and volume.
2. **Use the stoichiometry** of the balanced equation to calculate the required moles of NaOH.
3. **Convert moles of NaOH** to the corresponding volume in milliliters using its molarity.
4. **Input and compute** within the given interface to verify the calculations.
