Henry's law constant for the molality of methane in benzene at `298K `is `4.27xx10^(5)mm Hg`. Calculate the solubility of methane in benzene at `298 K` under `760 mm Hg`.

Explanation

To solve the problem of calculating the solubility of methane in benzene at 298 K under a pressure of 760 mm Hg using Henry's law, we can follow these steps:

### 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 proportional to the partial pressure of that gas above the liquid. The formula is:
\[
P = K_H \cdot X
