Hi! Priyanshu,

Rms speed of a gas is given by the formula:

μ rms = (3RT/M) ½

As you have asked for calculating rms speed at STPtherefore, temperature =298K,Molecular mass=28/1000 kg /mol. Now, you can calculate by using above formula. Keeping in mind that rms depends only on temperature.


Good luck!
