A `5L` cylinder contained `10` moles of oxygen gas at `27^(@)C`. Due to sudden leakage through the hole, all the gas escaped into the atmosphere and the cylinder got empty. If the atmospheric pressure is `1.0atm`, calculate the work done by the gas.

Explanation

To solve the problem, we need to calculate the work done by the gas when it escapes from the cylinder into the atmosphere. The work done by the gas during expansion can be calculated using the formula:

\[ W = -P \Delta V \]

where:
- \( W \) is the work done by the gas,
- \( P \) is the external pressure (atmospheric pressure),
- \( \Delta V \) is the change in volume.
