What is the mole fraction, x, of solute and the molality, m (or b), for an aqueous solution that is 18.0% naoh by mass?

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

  the mississippians were considered to be  horticulturalists, which means they were

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?
