Nitrogen dioxide (NO2) is a toxic gas produced by cars and factories. If a car produces one mole of NO2 during a 10 mile drive, how many grams of nitrogen dioxide are produced?

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.
