Question

Assume that an oil slick consists of a single layer of molecules and that each molecule occupies a cube 1.4 nm on a side. Determine the area of an oil slick formed by 1.1 m^3 of oil. Answer in units of m^2.

Answer 1

The area of oil slick is calculate as
`785.7 m^(2)`

Solution:

Volume of oil slick,
`V_(o) = 1.1 m^(3)`

The thickness of one molecule on a side, w = 1.4 mm =
`1.4* 10^(- 3)`

Now, in order to determine the area of oil slick,
`A_(o)`:

Volume, V =
`Area* thickness`

Thus

`Area,\ A_(o) = (V_(o))/(w)`

`Area,\ A_(o) = (1.1)/(1.4* 10^(- 3)) = 785.7 m^(2)`
