**Dissolution of Oxygen in Water at Variable Partial Pressures**

This exercise explores the solubility of oxygen (\( \text{O}_2 \)) in water under given conditions, focusing on how variations in partial pressures influence this solubility.

---

**Problem Statement:**

The partial pressure of \( \text{O}_2 \) in your lungs varies from 25 mm Hg to 40 mm Hg. Determine the mass of \( \text{O}_2 \) that can dissolve in 1.0 L of water at 25°C if the partial pressure of \( \text{O}_2 \) is 30 mm Hg.

**Given Data:**
- Henry's law constant for \( \text{O}_2 \), \( k_H(\text{O}_2) = 1.3 \times 10^{-3} \frac{\text{mol}}{\text{kg} \cdot \text{bar}} \) 

**Required:**

- Calculate the mass of \( \text{O}_2 \) in grams.

**Solution Steps:**

1. **Input Field**: There is a field provided to input the calculated mass of \( \text{O}_2 \).

2. **Action Buttons**:
   - **Submit Answer**: Submit your calculated value.
   - **Try Another Version**: Attempt the problem in a different version if needed.

3. **Note**: You have 1 attempt remaining to input the correct answer.

In summary, this problem requires applying Henry's Law to find out how much oxygen can dissolve in water under specific conditions. This knowledge is crucial for understanding gas exchange processes in respiratory and aquatic systems.
