Part B
Part complete
After calibration, you use the oleic acid/benzene solution to form a monolayer. It takes 8 drops , 9 drops and 6 drops before the layer on the water solution starts to make a bubble tha does not go into solution. What is the average number of drops for your monolayer?

Part C
Part complete
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.
0.383 mL |
Part D
Next we need to determine the mass of oleic acid in the monolayer. The concentration of the oleic acid/benzene solution is 0.02g/L. Calculate how many grams of oleic acid is in one drop.

Part E
sWith this information, we now need to 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.
1.12×10−6 |
mL/drop |
Part F
Determine the volume of the monolayer from the above information.

As part of Lab 11 you will make and standardize a solution of NaOH(aq). Suppose in the lab you measure the solid NaOH and dissolve it into 100.0 mL of water. You then measure 0.1993 g of KHP (204.22 g/mol) and place it in a clean, dry 100-mL beaker, and then dissolve the KHP in about 25 mL of water and add a couple of drops of phenolphthalein indicator. You titrate this with your NaOH(aq) solution and find that the...
Part I: You are instructed to produce solutions of H2S04 and NaOH for your lab experiment. The concentration you should produce is shown in the table below. Complete the table and copy it into your lab notebook for use during your lab. You will be provided with a 3.0 M stock solution of H2SO4 and solid NaOH. You will need to make 100 mL of each solution. H2SO4 Compound NaOH 0.9 Solution Concentration (M) 1.12 Moles in 100 mL 112...
Could you please help me to solve these question with all parts, including graph? thanks so much!! We were unable to transcribe this imagenumber of drops volume of solution, mL concentration, drops mL-1 (Eq. 6) For example, if the solution you use to determine the spectrum of the food dye, which we shall call "Solution 1," was prepared by adding 1 drop of food dye to 40.0 mL of distilled water, the concentration of the solution is found using Equation...
