Hi, i can't seem to answer the letter > an empty vial weighs 55.32 g. (a) if the vial weighs 185.56 g when filled with liquid mercury (d 13.53 g/cm3), what is its volume? (b) how much would the vial weigh if it were filled with water (d 0.997 g/cm3 at 25°

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?
