Here are the values i have from my experiment:
molar mass of stearic acid: 284.49 g/mol
density of solid stearic acid: 0.85 g/cm^3
concentration of stearic acid: 0.1 g/l
# of drops of stearic acid without residue +1 : 12 drops
diameter of water surface (cm): 14.8
automatic pipet sample volume: 25 ml
1.) total volume of stearic acid solution dispensed to make monolayer (micro l)
2.) grams of stearic acid dispensed to make the monolayer. use the concentration of stearic acid in hexane and the volume dispensed
3.) volume of stearic acid forming the monolayer. use the mass of stearic acid and the density of solid stearic acid to find this volume.
4.) area of stearic acid monolayer.
5) thickness of stearic acid monolayer. thickness = volume/ area
