Given that Avogadro's number is 6xx10^(2...

Given that Avogadro's number is `6xx10^(26)` per kg-mole and at normal temperature and pressure one kg-mole of a gas occupies `22.4m^(3)` volume, deduce the average distance between the gas molecules at NTP. Compare this with the amplitude of displacement wave when the intensity is 1 watt `m^(-2)` in air, taking effective frequency as 1000 Hz. Take `p=1.3kgm^(-3)` and `v=350ms^(-1)`
