An artificial spherical micelle is engineered to transport lipid-soluble drug molecules. A cross-sectional view passing through the center of this micelle shows a circular outer boundary made up of exactly 35 phospholipid molecules.
Calculate the estimated number of phospholipid molecules on the entire outer surface of this spherical micelle.
Assume the distribution of phospholipids is uniform across the entire outer surface of the micelle.
Use the formula:
