The speed of gas is calculated by a relation.
Root Mean square velocity µ(rms) = (3RT/M).
From this relation we can calculate speed.
Only mass could not be taken into consideration here because temperature is specified.
So after calculation.
Speed of Hydrogen gas = 157380 unit.
Speed of Methane gas = 68385 unit.
Speed of Nitrogen gas = 142356 unit.
Speed of oxygen gas = 46128 unit.
Plz say me the explaination
