A tea bag containing 15 grams of tea leaves with 0.7% of caffeine was used in solid-liquid extraction with 200ml of distilled water followed by liquid-liquid extraction using DCM. If 50.0mg of caffeine requires 10 ml of water and 3.0ml of DCM to be dissolved, how much caffeine can be extracted using 70.0ml of DCM? a. 4.8 x 10^-2 b. 5.7 x 10^-2 c. 3.8 x 10^-3 d. 5.8 x 10^-3
Please answer all 5 questions (it could be short answers). 5-1. What is the main barrier to separating liquid mixtures of less than 500 mL by distillation? 5-2. A sample mixture of ethyl benzoate (bp 212 Celsius) and dodecane (bp 216.2 Celsius) is injected on two GC columns. Column A has DC710 silicone oil as the stationary phase, and column B uses polyethylene glycol as the stationary phase. Which substance would be certain to elute first from column A and would the same material be expected to elute first from column B? Which column, A or B, would be expected to give the better separation of these two substances? 5-3. Question 5-2 refers to separating a mixture of two high boiling liquids by gas chromatography. These materials have similar boiling points. List several GC variables and conditions that would make it easier to separate thesesubstances by gas chromatography 5-4. Capillary GC columns have better resolution than packed columns even though the enormous surface area…

Indicate the appropriate protocol below to prepare the required solution. a) Solution 5 Preparation: Prepare: 10 mL of 23% mannitol From: solid mannitol Procedure: b) Solution 2 Preparation: Prepare: 0.5 liters of 0.01 mg/mL ascorbic acid From: solid ascorbic acid , MW = 176.1 g/mol Procedure: C) Solution 3 Preparation: Prepare: 1 liter of 150 mM Tris From: 1 Molar Tris stock solution Procedure:
2.1g of sample are dissolved in methylene chloride and the sample is extracted with aqueous solutions of acid and base. Three compounds are isolated - 0.8g of ethyl p-aminobenzoate, 0.6 g of acetanilide, and 0.5 g of benzoic acid. Calculate the % recovery for the procedure. (Round the answer to the nearest tens place.) Give just the number, not a % sign.)
A student rushed through this experiment. Describe the effect that the following procedural changes would have on the percent recovery of acetanilide. Briefly explain the basis of each answer.(a) Rather than adding 0.5-mL portions of boiling solvent to the acetanilide, the student added 5-mL portions of boiling solvent.(b) The student did not pre-heat the gravity filtration apparatus.(c) The student forgot to cool 5 mL of solvent in Part 5 and washed the crystals with room-temperature solvent.

6.0 mL of cyclohexanol, 8 mL of 85% phosphoric acid, and 10 drops of sulfuric acid are added to a 50-mL round-bottom flask with boiling chips, and the mixture is distilled into an ice-cooled receiver. The distillate is in the form of a colorless bi-phasic mixture. The cyclohexene upper layer is removed from the water layer, and dried over anhydrous calcium chloride. Isolated is cyclohexene as a clear and colorless foul-smelling liquid. Weighing data is given below. Gross mass: 51.24 g Tare mass: 48.04 g Product mass: 3.2g Question: Calculate the theoretical mass of the cyclohexene product, bearing in mind that the cyclohexanol starting material was measured by volume, not by mass (so you must use the density of cyclohexanol to convert milliliters to grams, before calculating the number of moles). Calculate the percent yield of cyclohexene obtained.
