The moles of MnO4- can be calculated by multiplying the volume of MnO4- required to reach the endpoint multiplied by the molarity of the MnO4- solution. What are the moles of MnO4- used in the titration?

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.
