### Explanation
This problem involves calculating the energy required to vaporize a given volume of water using its molar heat of vaporization. The key concepts include:
1. **Density of Water**: Water has a density of approximately 1 g/mL, which helps convert the volume into mass.
2. **Molar Mass of Water**: The molar mass of water (H\(_2\)O) is approximately 18.015 g/mol.
3. **Enthalpy of Vaporization**: The energy needed to change water from liquid to vapor at its boiling point is given by \( \Delta H_{\text{vap}} \).
### Approach
1. **Convert Volume to Mass**: Use the density of water.
2. **Convert Mass to Moles**: Use the molar mass of water.
3. **Calculate Energy**: Use the formula:
\[
\text{Energy (kJ)} = \text{moles of water} \times \Delta H_{\text{vap}}
\]
4. **Express Energy**: Provide the answer in kilojoules with three significant figures.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc319599a-7fb4-4ccd-84db-e0c8bd138b0d%2F2a6daef3-90db-41d5-bb0b-e0a5dc00e6a0%2Fah69ahg_processed.jpeg&w=3840&q=75)
