At normal temperature and pressur, 4g of He occupies a volume of 22.4 litre. Determine the speed of sound in helium. Take 1 atmospheric pressure `=10^(5)N//m^(2)` and `gamma` for helium `=1.67`.

Explanation

To determine the speed of sound in helium, we will use the formula for the speed of sound in a gas, which is given by:

\[ V = \sqrt{\frac{\gamma P}{\rho}} \]

Where:
- \( V \) is the speed of sound,
- \( \gamma \) is the adiabatic index (ratio of specific heats),
- \( P \) is the pressure,
