To determine which has the greater mass between water (H₂O) and oxygen (O₂), we need to compare their molecular weights.
1. **Mass of Water (H₂O)**:
The mass given is \(2.99 \times 10^{-26} \, \text{kg}\).
2. **Mass of Oxygen (O₂)**:
The mass given is \(2.66 \times 10^{-26} \, \text{kg}\).
Now, we can compare these two values directly:
- **Water (H₂O)**: \(2.99 \times 10^{-26} \, \text{kg}\)
- **Oxygen (O₂)**: \(2.66 \times 10^{-26} \, \text{kg}\)
Since \(2.99 \times 10^{-26} \, \text{kg}\) is greater than \(2.66 \times 10^{-26} \, \text{kg}\), we can conclude that water (H₂O) has the greater mass compared to oxygen (O₂).
**Conclusion**: Water has a greater mass than oxygen based on the provided values.
