At −11.0 ∘C (a common temperature for household freezers), what is the maximum mass of saccharin ( C7H5NO3S ) you can add to 1.50 kg of pure water and still have the solution freeze? Assume that saccharin is a molecular solid and neither ionizes nor associates when it dissolves in water.

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?
