At a constant temperature, a gas occupies a volume of `200 mL` at a pressure of `0.720"bar"`. It is subjected to an external pressure of `0.900"bar"`. What is the resulting volume of the gas?

Explanation

To solve the problem, we will use Boyle's Law, which states that at constant temperature, the pressure of a gas is inversely proportional to its volume. This can be expressed mathematically as:

\[ P_1 V_1 = P_2 V_2 \]

Where:
- \( P_1 \) = initial pressure of the gas
- \( V_1 \) = initial volume of the gas
- \( P_2 \) = final pressure of the gas
