You can obtain a rough estimate of the size of a molecule by the following simple experiment. Let a droplet of oil spread out on a smooth water surface. The resulting oil slick will be approximately one molecule thick. Given an oil droplet of mass 14.00 multiplied by 10-7 kg and density 1230 kg/m3 that spreads out into a circle of radius 41.8 cm on the water surface, what is the diameter of an oil molecule?
