One mole of an ideal monoatomic gas is mixed with 1 mole of an ideal diatomic gas The molar specific heat of the mixture at constant volume is .

Options

A. `3cal`
B. `4cal`
C. `8cal`
D. `9cal`

Explanation

To find the molar specific heat of the mixture at constant volume (\(C_v\)), we can follow these steps:

### Step 1: Identify the specific heat capacities of the gases
- For an ideal monoatomic gas, the molar specific heat at constant volume (\(C_{v1}\)) is given by:
\[ C_{v1} = \frac{3}{2} R \]
- For an ideal diatomic gas, the molar specific heat at constant volume (\(C_{v2}\)) is given by:
