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 of 7.61 × 10−7 kg and density of 912 kg/m3 that spreads out into a circle of radius 43.5 cm on the water surface, estimate the diameter of an oil molecule. answer in units of m. your answer must

Explanation:

We define density as

So, the volume for our oil will be

the volume for a cylinder with radius r and height h is

So, we can obtain the height of the droplet of oil as:

the radius is

And this is the diameter of the oil molecule.

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
