This is the problem:

"Suppose 300 cubic meters of oil is spilled into the ocean. Find the area of the resulting slick, assuming that it is one molecule thick and that each molecule occupies a cube 0.50 µm on a side."

Please help!

You have assumed that the molecues fit together perfectly. This is only a division problem.

= Number of Molecules

Where are you struggling, this setup or the unit conversion? - Sep 4th 2007, 12:47 PMtopsquark
(This is from the other thread.)

No. The area of the spill is not 600 . Keep track of your units.

The volume of the spill is

So

We know the volume of the spill and we know that the spill is one molecule thick, so

as TKHunny said.

Now get the units on top and bottom to be similar:

Always always*always*keep track of your units!
