At `0^(@)` and 760 mm Hg pressure, a gas occupies a volume of `100cm^(3)`. The Kelvin temperature of the gas is increased by one fifth, while the pressure is decreased by one fifth times. Calculate the final volume of the gas.

Explanation

To solve the problem, we will use the Ideal Gas Law, which states that for a given amount of gas, the relationship between pressure (P), volume (V), and temperature (T) is given by the equation:

\[ P_1 V_1 / T_1 = P_2 V_2 / T_2 \]

### Step-by-Step Solution:

1. **Identify Initial Conditions:**
- Initial volume, \( V_1 = 100 \, \text{cm}^3 \)
