A gaseous compound is 78.14 percent boron and 21.86 percent hydrogen .At 27degrees celicius ,73.4ml of the gas exerted a pressure of 1.12atm .If the mass of the gas was 0.0934g, what is it's molecular formulae

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.
