A stock solution of 75% v/v ethanol was diluted with distilled water to prepare 1L of 42% v/v ethanol. (Density of ethanol = 0.789 g/mL; MW of ethanol = 46 g/mol). Determine the initial volume (in mL) of 75% v/v ethanol used in the preparation. Final answer should NOT contain any unit. Type the VALUE only. Please observe 0 decimal places.
Extraction of Caffeine Post-lab 4. What does it mean for two solvents to be immiscible? 5. On the report sheet, you calculated your percent recovery of caffeine. a. If your percent was less than 90%, give at least one reason why it was less. b. A group of students have their percent yield more than 100%, give at least one reasonwhy it was more than 100%. Do NOT simply say “human error.” Be specific about the typesof errors (human or otherwise) that may have occurred, leading to a recovery more than eorequal to 100% (Is this possible Why?) 6. Based on what you observed during this experiment, is dichloromethane denser OR lessdense than water? Explain your reasoning. 7. Based on what happened in this experiment, is caffeine more soluble in water OR moresoluble in dichloromethane? Explain your reasoning. 8. Ethanol is miscible with water.

Spike recovery and detection limit. Species of arsenic found in drinking water include AsO32 3 (arsenite), AsO32 4 (arsenate), (CH3)2AsO2 2 (dimethylarsinate), and (CH3)AsO22 3 (methylarsonate). Pure water containing no arsenic was spiked with 0.40 mg arsenate/L. Seven replicate determinations gave 0.39, 0.40, 0.38, 0.41, 0.36, 0.35, and 0.39 mg/L.15 Find the mean percent recovery of the spike and the concentration detection limit (mg/L).

Pls do fast within 5 minutes and i will give like for sure Solution must be in typed form To plan a liquid–liquid extraction we need to know the solute’s distribution ratio between the two phases. One approach is to carry out the extraction on a solution that contains a known amount of solute. After the extraction, we isolate the organic phase and allow it to evaporate, leaving behind the solute. In one such experiment, 1.235 g of a solute with a molar mass of 117.3 g/mol is dissolved in 10.00 mL of water. After extracting with 5.00 mL of toluene, 0.889 g of the solute is recovered in the organic phase. If we extract 20.00 mL of an aqueous solution that contains the solute using 10.00 mL of toluene, what is the extraction efficiency?
A empty evaporating dish weighs 30.56g. You place 20.0mL of an NaCl solution in the dish plus the solution weighs 53.31g. You evaporatorate the solution to dryness ant find that the evaporatoring dish plus the residue weighs 32.25g. What is the w/v%? What is the w/w%? What is the molarity?
