- A mixture has thre components. The percentage of sand was determined to be 26.04%, the percentage of benzoic acid was determied to be 25.92%, and the percentage of salt was determined to be 35.97%. Calculate the total precent recovery.Based on this. What was the percentage error in the percentage of water in the sample, compared to pure MgSO4•7H2O?An oil sample had its iodine number determined using the pyridinium tribromide method. The sample and reagents used are as follows: Oil sample: 0.19 mL, density: 0.954 g/mL Pyridinium tribromide: 0.472 g Na2S203: 0.1 M, endpoint 27.68 mL %3D What is the approximate Bromine Number?

- helpYou're at the same pharmaceutical company, and they also make magnesium pills. You weigh out 5 tablets (3.2834 grams). And crush them with a mortar and pestle. You take a subsample of 384 mg and dissolve it in acid, making it to a final volume of 250mL. • You then take 50 mL and dilute it to 250mL volumetrically. • You further dilute the sample by taking 15 ml and diluting it to 250mL. • You run this on a varian AA with your standards and get the following response: Response (ABS) 0.546 1.134 2.135 1.634 ● ● Solution 1.0 ppm Mg 2.0 ppm Mg 4.0 ppm Mg Sample Calculate the amount of Mg in one pill. Line of best fit y = 0.5255x+0.0455Weigh out accurately 9.99 g of copper(II) sulfate pentahydrate (CuSO4·5H2O) by taring using a clean and dry empty 250-ml beaker. 2. Add tap water to the beaker to reach the 50-mL mark on the side of the beaker. 3. Dissolve all the crystals of CuSO4·5H2O in the water using a clean glass rod for stirring. 4. Then using a glass funnel transfer all the blue solution to a 100-mL volumetric flask. Rinse the beaker with about 10 mL of water and transfer the solution to the volumetric flask. Repeat the rinsing of the beaker with another 10 mL of water and transfer the solution to the volumetric flask. This is called quantitative transfer of the solution. 5. Then add enough water to reach the calibration mark of the volumetric flask. (You will need to use a dropper to add the last few drops of water to ensure the meniscus is on the calibration mark). Close the volumetric flask with a stopper and mix the solution well (so that it is homogeneous). 6. You have now prepared a standard solution (or…

- Show your complete solution and round-off your answers to four decimal places. A 0.1093-g sample of impure Na2CO3 was analyzed by the Volhard method. After adding 50.00 mL of 0.06911 N AgNO3, the sample was back titrated with 0.05781 N KSCN, requiring 27.36 mL to reach the end point. Calculate the % purity of the Na2CO3 sample. Answer = _% Na2CO3Gravimetric analysis is a quantitative method that involves measurement of volume of a solution of known concentration which is used to determine the concentration of the analyte.
