## Homework Statement

Assume that an oil slick consists of a single layer of molecules and that each molecule occupies a cube 0.792 nm on a side.

Determine the area of an oil slick formed by 1.56 m^3 of oil.

Answer in units of m^2.

## Homework Equations

1 nanometer = 1.0E9 meters

## The Attempt at a Solution

.792 nm = 7.92E-10 m

(1.56 m^3) / (7.92E-10 m) = 1.97E9 m^2

I think I'm doing everything right, but it's coming up as wrong...could someone please look through my work and point out anything I'm doing wrong?

That would be much appreciated, thanks!
