Ten drops of olive of radius 0.20 mm spread into a circular film of radius 14.6 cm. on the surface of water. Estimate the size of an oil molecule.

Explanation

To estimate the size of an oil molecule based on the given information, we can follow these steps:

### Step 1: Calculate the volume of one drop of olive oil
The volume \( V \) of a single drop can be calculated using the formula for the volume of a sphere:
\[ V = \frac{4}{3} \pi r^3 \]
where \( r \) is the radius of the drop. Given that the radius of one drop is \( 0.20 \, \text{mm} \) (which is \( 0.20 \times 10^{-1} \, \text{cm} = 0.02 \, \text{cm} \)), we can substitute this value into the formula.
