Part 1. One gram of caffeine dissolves in 55 ml of water; 7 ml of dichloromethane (DCM); 530 ml of diethyl ether; and 100 ml of benzene. Covert the solubility of caffeine in these four solvents into units of mg/ml. a) Solubility of caffeine in mg/ml in water: b) Solubility of caffeine in mg/ml in DCM: c) Solubility of caffeine in mg/ml in Diethyl Ether: d) Solubility of caffeine in mg/ml in Benzene: Which is the optimal solvent to extract caffeine from an aqueous solution? Why? Part 1 Continued: Use intermolecular force (IMF), provide a brief explanation on the solubility of caffeine in water, diethyl ether, observed above. (Hint: draw the skeletal structures for caffeine, DCM and diethyl ether)
What is the freezing point (°C) of a solution prepared by dissolving 13.5 g of (NH4)2SO4 (formula weight = 132 g/mol) in 100 g of water? The molal freezing point depression constant for water is 1.86°C/m. Assume complete dissociation in solution. Express your answer in decimal notation and to 2 decimal places, without units.
Why does the molarity of NaOH usually have to be standardized? When preparing the aqueous NaOH, the exact volume of the NaOH used cannot be measured due to water being hygroscopic. Solid NaOH can react with acid very easily and therefore the initial mass of the base may not be exact. When dissolving the solid NaOH in pure distilled water, the exact volume of the NaOH used cannot be measured due to buret calibration. Solid NaOH can react with water in the air very easily and therefore the initial mass of the base may not be exact.
100mL of a 0.100M solution of NaCl is prepared (standard solution). This solution will be used to standardize a AgNO3 solution. Since the concentration of AgNO3 changes slightly with time, it has to be standardized. The exact concentration of AgNO3 is determined using the 0.100M NaCl solution. Calculate the mass of NaCl that is necessary to prepare the standard solution.
You are given an 18% solution of sodium imidazole. What mass of imidazole (in g) would be in 20 mL of this solution? a.

2. You have a solution that contains 4.0g of oxalic acid dissolved in 100 mL of water. This solution is placed in a separatory funnel, and then 100 mL of diethyl ether is added to the separatory funnel and an extraction is performed. (Diethyl ether and water are immiscible solvents.) Use the following constants to calculate how much oxalic acid is in each solvent after the extraction. Solubility of oxalic acid in water = 9.5 g / 100 mL Solubility of oxalic acid in ether = 16.9 g/100 mL
he Don Juan Pond in Antarctica has one of the highest salt concentrations of any natural body of water on Earth. Even though it is in one of the coldest places on the planet, it almost never freezes due to this high salt content. The density of the pond water averages 1.3 g/mL. a.) Calculate the mass (in grams) of 1 gallon of water from the Don Juan Pond. b.) The dissolved salts are dominated by calcium chloride and the pond water is 44% salt by mass. What is the mass (in grams) of the salt in 1 gallon of the pond water? c.) If the salt is all CaCl2, what would be the molarity of the pond water?
