Determination of the Molecular Weight of an Unknown Compound by Freezing Point Depression LAB EXPERIMENT BY: Long, Loren; Pratt, Lailah; Thomas, Sydney, and Dr Kokougan Allado Procedure Safety: You must wear safety goggles throughout the experiment. Benzophenone is relatively safe but it must be disposed of in the container provided for this purpose in the hood. Use acetone to rinse your equipm...

OBJECTIVES Upon completion of this laboratory, students should be able to calculate mass percent of an unknown hydrate; describe the technique of gravimetric analysis; and assemble the apparatus for evaporation water from a hydrate. Gravimetric analysis, by definition, includes all methods of analysis in which the final stage of the analysis involves determining the amount of material present b...

Part II: Fluorescein 1. Obtain 50 mL of the fluorescein stock solution. 2. After rinsing the pipet three times with 15mL of the stock solution, pipet exactly 10.00 mL into a clean dry 250 mL Erlenmeyer flask. 3. Repeat the previous step twice more so that you have three flasks with 10 mL of the stock solution in each of them. 4. Rinse your pipet three times with distilled water. 5. Rinse your p...
