A drop of olive oil of radius 0.30 mm spreads into a nearly circular film of radius 12 cm on the water surface. Estimate the molecular size of olive Oil

Explanation

To estimate the molecular size of olive oil based on the given problem, we can follow these steps:

### Step 1: Understand the Problem
We have a drop of olive oil with a radius of 0.30 mm that spreads into a circular film with a radius of 12 cm. We need to find the molecular size of the olive oil, assuming that the film is one molecule thick.

### Step 2: Convert Units
Convert the radius of the olive oil drop from millimeters to centimeters for consistency.
- Radius of the drop, \( r = 0.30 \, \text{mm} = 0.030 \, \text{cm} \)
