The speed of sound in hydrogen gas at certain temperature is v `(m)/(s)` Find the speed of sound in a gaseous mixture containing 2 moles of oxygen and 1 mole of hydrogen gas, at the same temperature. Assume the gases do no react at the ordinary temperature.

Explanation

To find the speed of sound in a gaseous mixture containing 2 moles of oxygen and 1 mole of hydrogen gas at a certain temperature, we will follow these steps:

### Step 1: Identify the given data
- Moles of oxygen (O₂), \( n_1 = 2 \)
- Moles of hydrogen (H₂), \( n_2 = 1 \)
- Speed of sound in hydrogen, \( v \) (m/s)
- Specific heat ratio for oxygen, \( \gamma_1 = \frac{7}{5} \)
- Specific heat ratio for hydrogen, \( \gamma_2 = \frac{7}{5} \)
