At same temperature, oxygen is more soluble in water than hydrogen. Which of them will have a higher value of `K_(H)` and why?

Explanation

To solve the question, we need to understand the relationship between the solubility of gases in water and Henry's law, specifically the Henry's constant \( K_H \).

### Step-by-Step Solution:

1. **Understand Henry's Law**: Henry's law states that the amount of gas that dissolves in a liquid at a given temperature is directly proportional to the partial pressure of that gas above the liquid. The relationship can be expressed mathematically as:
\[ K_H = \frac{P}{C} \]
