![**Problem Statement: Lake pH Neutralization**
A lake has been acidified to a pH of 4.325. If the lake has a volume of \(9.65 \times 10^4\) cubic meters, what mass, in kg, of CaO (calcium oxide) must be added to raise the pH to a value of 7.00?
**Hint:**
The reaction of CaO with water is:
\[ \text{CaO} + \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 \]
**Input Box:**
- **kg CaO:** [This is where you input your answer]
