in an experiment to estimate the size of an oil molecule ,the diameter of the patch was measured to be200mm for an oil drop of radius 0.25mm. Determine the diameter of the molecule of the oil

Answer 1

First, calculate the diameter of the oil drop:
Diameter = 2 x radius
Diameter = 2 x 0.25mm = 0.5mm

Now, let's calculate the diameter of the oil molecule using the ratio of the diameter of the oil drop to the diameter of the oil molecule:

Ratio = Diameter of oil drop / Diameter of oil molecule

200mm / Diameter of oil molecule = 0.5mm

Diameter of oil molecule = 200mm / 0.5
Diameter of oil molecule = 400mm

Therefore, the diameter of the oil molecule is 400mm.
