- What is the calibration correction of a 10-mL pipet that delivers 9.9300 g of H2O at 19.0°C which is weighed against brass weights?A pipet is used to transfer 6.00 mLmL of a 3.75 MM stock solution in flask “S” to a 25.00-mL volumetric flask “A,” which is then diluted with DI H2OH2O to the calibration mark. The solution is thoroughly mixed. Next, 10.00 mLmL of the solution in volumetric flask “A” is transferred by pipet to a 50.00-mL volumetric flask “B” and then diluted with DI H2OH2O to the calibration mark. Calculate the molarity of the solution in volumetric flask “B.”A pharmacist receive a prescription for ear drop, calling for 0.05 mL of glacial acetic acid, 2 mL of glycerin and 8 mL of purified water. Using a 10 mL graduated cylinder calibrated in 0.5 mL units, explain how the required quantity of glacial acetic acid could be obtained.
- A pipet is used to transfer 5.00 mL of a 1.25 M stock solution in flask “S” to a 25.00-mL volumetric flask “B,” which is then diluted with DI H2O to the calibration mark. The solution is thoroughly mixed. Next, 3.00 mL of the solution in volumetric flask “A” is transferred by pipet to a 50.00-mL volumetric flask “B” and then diluted with DI H2O to the calibration mark. Calculate the molarity of the solution in volumetric flask “B.”Oral rehydration salts are stated to contain the following components: Sodium Chloride 3.5g Potassium Chloride 1.5g Sodium Citrate 2.9g Anhydrous Glucose 20.0g 8.342 g of oral rehydration salts are dissolved in 500 ml of water. 5 ml of the solution is diluted to 100 ml and then 5 ml is taken from the diluted sample and is diluted to 100 ml. The sodium content of the sample is then determined by flame photometry. The sodium salts used to prepare the mixture were: Trisodium citrate hydrate (C6H5Na3O7, 2H2O) MW 294.1 and sodium chloride (NaCl) NW 58.5. Atomic weight of Na = 23. The content of Na in the diluted sample was determined to be 0.3210 mg/100 ml. Determine the % of stated content of Na in the sample.

- 5.1g of toothpaste was weighed out and transferred to a 500 ml beaker. 250 ml of deionized water was added to the beaker by measuring cylinder, heated for 5 minutes on a hotplate, then sonicated for 10 minutes in an ultrasonic bath. The contents of the beaker was then transferred to a 1000 ml volumetric flask, made to the mark with deionized water and mixed thoroughly. Ten ml of this solution was removed from the volumetric flask (autopipette), 5 ml (measuring cylinder) of TISAB buffer was added. The concentration of the toothpaste obtained is 3.4mgF-/L, calculate the % of fluoride (F) in toothpaste.give two examples of internal standards for menthol and thc analysis.pleasee convert this with solution 759g-cg 466.75qt-mL 610.76min-ms
