Calculate `gamma` of a gaseous mixture consisting of 3 moles of nitrogen and 2 moles of carbon dioxide.

Explanation

To calculate the value of \( \gamma \) (the heat capacity ratio) for a gaseous mixture consisting of 3 moles of nitrogen (N₂) and 2 moles of carbon dioxide (CO₂), we can follow these steps:

### Step 1: Identify the number of moles
We have:
- \( n_1 = 3 \) moles of nitrogen (N₂)
- \( n_2 = 2 \) moles of carbon dioxide (CO₂)

### Step 2: Calculate total moles
