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 problem, we need to understand the relationship between the solubility of a gas in a liquid and its Henry's law constant (K_H). Here’s a step-by-step breakdown of the solution:

### Step 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 mathematical expression for Henry's Law is:
\[ K_H = \frac{P}{C} \]
where:
- \( K_H \) is the Henry's law constant,
- \( P \) is the partial pressure of the gas,
