Z for ideal gas is...........

Explanation

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

### Step-by-Step Solution:

1. **Understanding the Compressibility Factor (Z)**:
- The compressibility factor (Z) is a measure of how much a real gas deviates from ideal gas behavior. It is defined by the equation:
\[
Z = \frac{PV}{RT}
