Find the speed of sound in a mixture of `1` mole of helium and `2` mole of oxygen at `27^(@)C`

Explanation

To find the speed of sound in a mixture of 1 mole of helium and 2 moles of oxygen at 27°C, we will follow these steps:

### Step 1: Identify the formula for the speed of sound in a gas mixture
The speed of sound \( V \) in a gas is given by the formula:
\[ V = \sqrt{\frac{\gamma RT}{M}} \]
where:
