.102 g pure caffeine is added to .1 mL methylene chloride and .1 mL water, shaken and allowed to separate. the water is removed and the remaining liquid is mixed with sodium sulfate. This is dry filtered with an additional .5 mL water into a flask. The remaining liquid is heated, leaving the solid behind. What is the caffeine's theoretical yield? Density of CH2Cl2 is 1.3255.

Also, I started by finding by the KD = solubility in organic solvent (g/100mL) / solubility of water (g/100 mL) = (.102g/.1)/(.102/.1) = 1, please let me know if this is also correct.

Ethylene chloride, ClCH2CH2Cl (98.96 g/mol, density = 1.26 g/mL, bp = 83 °C), is an organic solvent with polarity similar to methylene chloride, and is also not miscible with water. a) If substituted for methylene chloride in this partition coefficient experiment, would ethylene chloride form the top or bottom layer? b) Provide an explanation, using appropriate data to support your answer. c) Despite the similarities, methylene chloride is superior to ethylene chloride as an extraction solvent. Why?

Below is the background info for the lab assignment. The 4 blank boxes are the questions I would like answers too. The end point for the fine titration was 35.90 mL in the burette when the solution turned bright green again. And the coarse titration I got 35.36mL as the end point. 35.9 mL is exact in case you need that info. Thanks! Background In this lab, we will determine the amount of alcohol (ethanol), C2H5OH, in a commercial vodka...
