In the evening, after the sun sets, will the wind blow toward the land, or toward the
water?

Calculate the number of molecules present in 0.750 mol of mgo.

Which of these is a physical property

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.
