1. Estimate the area of a one-molecule-thick oil film formed by spreading 2 ml of oil on the surface of water. Assume that an oil molecule is roughly 15 nm in length. Show your work. 2. If we will be conducting the experiments in tanks with dimensions of roughly 10 in by 10 in. Estimate the volume of oil you would need to cover half the total area. Again assume a molecule is 10 nm in size. Show your work.
3. Estimate the number of molecules in 1 ml of oil assuming they’re 10 nm in size. What assumptions do you have to make? Show your work.
