What is the molar mass of argon?

What is a possible quantum number set for an electron in the 3s orbital of a magnesium atom

From the choices provided below, list the reagent(s) in order that will react with cyclopentanone to form the compound shown below.

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.
