H2 molecules are diatomic molecules. According to statistical thermodynamics, the RMS speed of a diatomic molecule is determined by
(1/2)mvrms2 = (5/2)kT
m = mass of a single H2 molecule
T = absolute temperature = (25 + 273) Kelvin
k = Boltzmann constant
vrms = √(5kT/m)
Plug in the numbers to get vrms.
