The `C_(p)` and `C_(v)` of a gas are 20.834 and `12.520 J K^(-1) "mol"^(-1)` respectively.What is the atomicity of the gas.

Explanation

To determine the atomicity of the gas using the given values of \( C_p \) and \( C_v \), we can follow these steps:

### Step 1: Understand the relationship between \( C_p \) and \( C_v \)
The relationship between the specific heat capacities at constant pressure (\( C_p \)) and constant volume (\( C_v \)) is given by the formula:
\[ \gamma = \frac{C_p}{C_v} \]
where \( \gamma \) (gamma) is also known as the heat capacity ratio.
