Classify the molecules as hydrophilic, hydrophobic, or amphipathic (amphiphilic).

Since there are no molecules to classify, the best I could do is to discuss as much what are the characteristics of molecules that are classified as hydrophilic, hydrophobic, or amphipathic (amphiphilic). Hydrophilic molecules are molecules which are "water-loving" which means they are dissolved in water. These molecules are polar molecules. Examples are salt, milk and soap. Hydrophobic molecules are molecules which are "water-fearing" which means they do not dissolve in water. Examples are oils, fatty acids and soap. As you can see from the examples, soap is written in both. This is because soap has both hydrophobic end and hydrophilic end which makes it an amphiphatic or amphiphilic molecule.
