  • root mean square velocity = √3RT/molecular weight of the gas
    therefore,
    Vrms is inversely proportional to root of molecular weight of the gas.
    Vrms(O2)/Vrms(H2)=√Mw.weight of H2/Mw.weight of O2

    root mean square velocity of oxygen is C m/s.
    therefore,
    root mean square velocity of H2 is 4C m/s.
