If you had stearic acid in a hexane solution and some of the hexane evaporated, what would happen to the Avogadro’s number and why?
Thank you.

1. The stearic acid/hexane solution contains 0.1 g of stearic acid per 1 mL of solution. What is the molarity of this solution?
What would happen if you had used a 1:1 mixture of ethyl acetate instead of hexane to elute your column? Would the product (DEET) have come out faster or slower? Would this have improved your separation, or made it worse?
If you added too much acetic acid to the milk solution , what would happen to the lactose? Please, draw the products of the reaction that would occur. Thank you!
You determined the molar mass of an unknown fatty acid 3 dissolved into stearic acid to be 219.4 g/mol. Unknown fatty acid 3 was myristic acid, which has a molar mass of 228.37 g/mol. What was your percent error to the correct number of significant figures?
If you failed to dry the ether solution before evaporating it, what would you see in the flask after the ether had evaporated, how would this affect your yield, your melting point?
Question 16 (1 point) Suppose some blood cells were in a hypertonic solution. What would happen to them? They would shrink. They would remain the same size. They would expand. The outcome is not predictable.
6.90. Benzene and hexane are being considered as solvents to extract acetic acid from aqueous mixtures At 30°C, distribution coefficients for the two solvents are KB-0.098 mass fraction acetic acid in benzene/mass traction acetic acid in water and KH 0017 mass fraction acetic acid in hexane mass fraction acetic acid in water (a) Based on the distribution coefficients only, which of the two solvents would you use and why? Demonstrate the logic of your decision by comparing the quantities of...
Name: Date: Instructor's Initials: Lab Section: Enthalpy PreLab What would happen if you used a wet beaker to obtain your acid solution? How might this affect your results? 2. What is the difference between heat capacity and specific heat? 3. What is the purpose of using volumetric glassware for this experiment? 4. Why rinse the pipet three times with the solution to be used? How many ml of solution should be used to rinse the 100.00 mL pipet-5 mL, 10...
POST-LAB QUESTIONS 1. What would happen if you added more than 5 mL of yeast solution to the H2O2? 2. What would happen if you added more than 5 mL of H2O2 to the 5 mL of yeast solution?
Please show work so I can better understand why. Thank you What does "essential fatty acid" mean? Draw the structural formula of glycerol What is a triacylglycerol or triglyceride? Draw the condensed structural formula for the triglyceride made of linoleic acid, linolenic acid and stearic acid What is the function of triglycerols in the body?
