    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.
