A mixture is made of two or more materials that a) cannot be separated by any means.
b) cannot be separated by any means.
c) can be separated by physical means.
d) cannot be separated by physical means.

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
