Part E What is the typical rotational frequency frot for a molecule like N2 at room temperature (25 °C)? Assume that d for this molecule is 1 A = 10¬10 m. Take the total mass of an N2 molecule to be mN, = 4.65 × 10¬26 kg. 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. ? frot Hz %D Submit Request Answer
