In the si system of units, the mole is one of seven base units. it is frequently used in chemical calculations. however, a mole of something is just a particular quantity of it. it is not a unit of measure in the way that meters, seconds, and kilograms are. calculations performed with the number of moles of a substance could also be performed with the number of particles of a substance. based on this information, do you think that the mole should be considered a base unit in the si system? explain why or why not.

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?
