You can obtain a rough estimate of the size of a molecule with the following simple let a droplet of oil spread out on a fairly large but smooth water surface. the resulting oil slick that forms on the water will be approximately one molecule thick. given an oil droplet with a mass of 9.00 x 10^-7 kg and a density of 918 kg/m^3 that spreads out to form a circle with a radius of 41.8 cm on the water
what is the approximate diameter of an oil molecule?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
