What do you think are some of the errors involved in calculating Avogadro's number by spreading oil on pond?

Question

10 point for those who have the best and detailed answer/// Thanks...i really need it... very urgent......

Answer 1

My freshman class does a similar experiment using an organic acid.  Some of the issues that arise are...

Measuring the spill area.

Assumptions about the shape of the molecules and their orientation.

These two have to do with calculating the volume of the "spill".  Coupled to molar mass, you can figure out how many molecules you have, BUT you are assuming that the molecules are all neatly alligned the same way (and you know which way that is) and that you can accurately measure the area.  These typically contribute to the final error.

I'm sure a few more will come to mind.
