interstellar space has an average temperature of about 10 K and an average density of hydrogen atoms of about one hydrogen atom per cubic meter. calculate the mean free path of hydrogen atoms in interstellar space.use d= 100 pm as the diameter of a hydrogen atom.
The equation for mean free path is:
or easier to see here:
where λ is mean free path,
d is diameter of a hydrogen atom in m. (for you, 100pm = 10^-10 m)
and n is the # of atoms per cubic m (for you, 1 per m^3)
so just plugging these into the equation yields: 2.251 *10^19 meters.
