what is the average displacement of melocules of a solid when vibrating in room temperature (about 23 Celsius)

Question

all molcules of solids are bonded to one another,but they are vibrating around their place what is the approximate displacement of moleculs around their bonding-point? I think it could be in range of micron. is it possible that range of vibration to be approximated in millimeters in room temperature?

Answer 1

The displacement would be less than the average inter molecular separation in the solid, which you can estimate from the density and the molecular weight. I think your displacement values are way too high.
