The values of critical pressure, critical volume and critical temperature for hydrogen gas are 12.97bar, `0.005 Lmol^(-1)` and 33.2K. Calculate the compressibility factor.

Explanation

To calculate the compressibility factor (Z) for hydrogen gas using the given critical properties, we can follow these steps:

### Step-by-Step Solution

1. **Identify the Formula for Compressibility Factor (Z)**:
The compressibility factor (Z) can be calculated using the formula:
\[
Z = \frac{P_c \cdot V_c}{R \cdot T_c}
