Micelles and Biological Membrane

Micelles are the type of lipid molecules that organize themselves in spherical shape in aqueous solutions. The production of the micelle is a reply to the amphipathic behavior of fatty acids. It means that they consist of both hydrophobic regions and hydrophilic regions. In micelles, polar head groups (hydrophilic groups) produce an outer layer associated with water whereas nonpolar tails (hydrophobic groups) are organized in the interior.

You set out to determine the density of lead in the laboratory. Using a top loading balance to determine the mass and the water displacement method (Study Question 41) to determine the volume of a variety of pieces of lead, you calculate the following densities: 11.6 g/cm3, 11.8 g/cm3, 11.5 g/cm3, and 12.0 g/cm3. You consult a reference book and find that the accepted value for the density of lead is 11.3 g/cm3. Calculate your average value, percent error, and standard deviation of your results.
