This is my Lab 7 for Chemistry, Writing a chemical equation from titration data. I have looked at it repeatedly and I just cannot wrap my head around how to find the answer. I have to find the moles of NaOH, H3PO4 used for each experiment (Bromcresol Green Titration, Phenolphthalein Titration) using g/ml and ml. Then the bottom equation needs balanced from that data.

This is my Lab 7 for Chemistry, Writing a chemical equation from titration data. I have looked at it repeatedly and I just cannot wrap my head around how to find the answer. I have to find the moles of NaOH, H3PO4 used for each experiment (Bromcresol Green Titration, Phenolphthalein Titration) using g/ml and ml. Then the bottom equation needs balanced from that data.
![**Bronsted/Green Titration:**
- **NaOH:**
- Concentration in g/mL: 0.0040g/mL
- Volume of each used (mL): 9mL
- Moles of each used: (Not specified)
- **H₃PO₄:**
- Concentration in g/mL: 0.00297g/mL
- Volume of each used (mL): 30mL
- Moles of each used: (Not specified)
**Phenolphthalein Titration:**
- **NaOH:**
- Concentration in g/mL: 0.0040g/mL
- Volume of each used (mL): 33mL
- Moles of each used: (Not specified)
- **H₃PO₄:**
- Concentration in g/mL: 0.00297g/mL
- Volume of each used (mL): 30mL
- Moles of each used: (Not specified)
- **Mole ratio = Moles NaOH / Moles H₃PO₄**
**Balance Equation:**
\[ n \text{ NaOH} + \text{H}_3\text{PO}_4 \rightarrow \text{Na}_n\text{H}_{3-n}\text{PO}_4 + \text{n H}_2\text{O} \]
**Instructions:**
1. Use a buret to titrate with standard NaOH solution. Ensure proper usage.
2. Record data on the table provided, making sure to measure accurately.
3. Balance the chemical equation as part of the titration analysis.
**Note:**
Ensure all calculations are accurate and thorough. The data should be complete for effective analysis.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb174096e-7de4-4e82-a75d-00bdbc908b15%2Fcac88993-271f-45cc-9882-eb97d5cadbe5%2Fgqjky7g_processed.jpeg&w=3840&q=75)
