A. Using the graduated cylinder, you calibrate the pipet you will be using and the values you collect are as follow. What is the average number of drops per mL of benzene. 18 drops, 21 drops, 17 drops.
B. After calibration, you will use the oleic/benzene solution to form a monolayer. It takes 8 drops, 9 drops, and 8 drops before the layer on the water solution starts to make a bubble that does not go into solution. What is the average number of drops for your monolayer?
C. Since we have the number of drops it takes to make a monolayer and we have the number of drops it takes to make one mL of benzene, we can determine the mL of oleic acid/benzene it takes to form a monolayer.
D. Next we need to determine the mass of oleic acid in the monolayer. The concentration of the oleic acid/benzene solution is 0.02 g/mL. Calculate how many grams of oleic acid is in one drop.
E. With this information, we need to now calculate the volume in milliliters. We need to know how many mLs a drop of oleic acid occupies using the density of 0.895 g/mL and the number of drops of oleic acid solution used.
F. Determine the volume of the monolayer from the above information.
