A mixture of xenon and nitrogen gases contains xenon at a partial pressure of 571
mm Hg and nitrogen at a partial pressure of 156 mm Hg. What is the mole fraction of
each gas in the mixture?

Please look at the picture above

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion. what is the frequency f of oscillation?
