Different between methane and ethane.​

0.09 moles of sodium sulfate in 12 ml of solution

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.

Ineed pls urgent 1-20 in order and fully detail step my step.
