The molar heat capacity of a gas at constant volume is found to be `5 cal mol^(-1) K^(-1)`. Find the ratio`gamma = C_p/C_v` for the gas. The gas constant `R=2 cal mol^(-1) K^(-1).

Explanation

To find the ratio \( \gamma = \frac{C_p}{C_v} \) for the gas, we can follow these steps:

### Step 1: Identify the given values
- Molar heat capacity at constant volume, \( C_v = 5 \, \text{cal mol}^{-1} \text{K}^{-1} \)
- Gas constant, \( R = 2 \, \text{cal mol}^{-1} \text{K}^{-1} \)

### Step 2: Use Mayer's equation
Mayer's equation relates the heat capacities at constant pressure and volume:
