Acetaminophen or paracetamol, the active ingredient in many pain killers absorbs in the UV range with a λmax at 250 nm in neutral solutions (methanol usually). Its extinction coefficient is 14 mM-1cm-1. Each commercially available tablet (Tylenol, Panadol or Herron) contains 500 mg paracetamol. Its molecular weight is 151.1. Using this information, calculate the dilution required to analyse the concentration of paracetamol in a commercially available paracetamol tablet. Start by dissolving the tablet in 100 mL methanol. Show working out.
Thank you. 0.02 kg plant extract in 2dm3 of water was shaken with 0.1dm3 ether. Upon checking, 1.7x10-3 kg of plant extract passes into the ether. note that there are no changes in the molecular state of the plant extract. what amount of the plant extract was left unextracted if the aqueous solution was shaken with 0.1dm3 ether the second time?

Preparation of 0.25N NaOH Objective: Apparatus and Materials: Procedure : Calculate the exact mass of NaOH needed to prepare 1.0L of 0.25N NaOH for standardization. Show your computations. Using the triple beam balance, weigh the desired amount of NaOH. Place the weighed amount of NaOH into the 500 mL volumetric flask and add distilled water until it reaches the mark. Agitate and transfer the solution into the reagent bottle. Add again distilled water to the same volumetric flask until it reaches the mark and pour it to the same reagent bottle, thus having a total volume of 1.0 L. Label the reagent bottle, 0.25N NaOH. Data and Computations: Conclusion:
Topic: Isolation of Crude Ovalbumin from Egg White by Ammonium Sulfate Precipitation(Salting Out) After filtration, 30.0 mL of the filtrate was obtained, and the solution was brought from 0% to 40% saturation by adding the required amount of powdered ammonium sulfate, (NH4)2SO4. Why is there a need to gradually add the ammonium sulfate to the sample?
Tim is interested in analyzing for Pyraclostrobin (pesticide) in strawberries using QuECHers method for extraction and clean up before analysis with HPLC-uv. The concentration of the Pyraclostrobin in the fruits that he sampled is thought to be between 1-10 ng pesticide per g fruit fresh weight. The HPLC-uv instrument he is using has a LoQ of 5 ppb for Pyraclostrobin. Tim is starting out with 500 mg of the sliced fruit
Based on TLC, how can you tell if the reaction is complete and what is the relevvance of the multiple marks in the lanes of the tlc? PROCEDURE To a six inch test tube was added thiamine hydrochloride (0.65 g), followed by water (2mL). The mixture was gently shaken until homogeneous, and then ethanol (7.5 mL)was added. Finally, sodium hydroxide (10%, 1.5 mL) was added and the mixture wasgently stirred to ensure complete mixing.Benzaldehyde (3.8 mL) was then added at room temperature in one portion with gentlestirring. The pH of the resulting reaction mixture was determined and adjusted to >10by dropwise addition of 10% sodium hydroxide. The reaction mixture was then partiallysubmerged in a 65 °C water bath2 and the progress of the reaction was periodicallymonitored by TLC analysis.Once TLC analysis indicated that the reaction was complete, the reaction mixture wascooled to approximately room temperature, and then chilled in an ice-water bath. Theresulting precipitate was collected by…

The label is a reagent to which he had specified on the label only the alcohol name and molecular formula of the same which was C4H10O. At the beginning of the experiment, about 50 mg reagent was diluted in deuterated chloroform with standard internal TMS and then added a specific vial (tube) for analysis of 1H and 13C spectra. When operating the equipment and ending the experiment, the teacher of discipline two being a spectrum of each 1H and one of 13C, and requests that they indicate which structure was responsible for those chemical spectra. Do you know those hired to the students who are here, qualify the structure of the referred responsible for the set of 13C and 1H spectra, as requested by the teacher.
