    What's the average speed of hydrogen molecules at room temperature and how do you figure it out? Is there an equation?

    V = sqrt(3*T*k/m)

    T = absolute temperature (in Kelvin)
    k = Boltzman constant = 1.3805*10^-23 J/K
    m = mass of the gas particle

    For anything in thermal motions and gases look up "Boltzman"
