The value of compressibility factor for an ideal gas is equal to 1.

Explanation

To solve the question regarding the compressibility factor (Z) for an ideal gas, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Compressibility Factor (Z)**:
The compressibility factor (Z) is defined as the ratio of the volume of a real gas to the volume of an ideal gas under the same conditions of temperature and pressure.
\[
Z = \frac{V_{\text{real}}}{V_{\text{ideal}}}
