The protein in a 0.2976 -g sample of cheese is determined by the Kjeldahl method. The sample is digested with H2SO4, the resulting solution made basic with NaOH, and the ammonia distilled into 50.00 mL of 0.09756 M HCl. The excess HCl is then back titrated using 39.87 mL of 0.05345 M NaOH. Calculate the % N and % protein of the sample.
A 1.43 x 10-4 L solution of 45.7 mg/mL protein was analyzed using the Kjeldahl procedure. After digestion of the protein, the liberated NH3 was collected in 9.80 mL of 0235 M HCl. The unreacted acid required 10.75 mL of a standard solution of 0.0149 M NaOH for complete titration. Calculate the weight percent of nitrogen in the protein. (Molar mass N = 14.00674 g/mol)
For breakfast, the nihilistic Rick Sanchez ate 100 g of cereal mixed with 20 g of milk. A 1.500 g sample of the same cereal was analyzed using the Kjeldahl method, and the liberated NH3 was distilled into 50 mL of a 0.0227 M HCl solution, and back-titrated with 2.85 mL of 0.0112 M NaOH solution. A 1.100 g sample of milk was also analyzed, and the liberated NH3 was distilled into 55 mL of a 0.0234 M HCl solution, and back-titrated with a 3.10 mL of 0.0121 M NaOH. Use the values: MM N=14.07 g/mol. meat= 6.25 dairy= 6.38 cereal= 5.70 What is the % protein in the cereal sample? What is the % protein in the milk sample?
To determine the concentration of an EDTA solution, the following zinc(II) solution is prepared: metallic zinc (m(Zn) = 0.301 g) is dissolved in dilute sulfuric acid, the resulting solution is poured into a volumetric flask with a volume of 1.00 L and is filled to the graduation mark with water. The titration of an aliquot of zinc(II) solution with a volume of 20.00 ml consumes (14.42 ml; 14.40 ml; 14.48 ml; 14.44 ml; 14.49 ml) of EDTA. Calculate the concentration of EDTA solution with accuracy corresponding to the starting data, give confidence interval.
25 g of the dilute mixture of H2SO4 and HNO3 is completed to 500 mL with water. When BaCl2 is added to 10 mL of this solution, the precipitate obtained is 362 mg. Another 20 mL portion taken from the solution is neutralized with 39.2 mL of 0.2 M NaOH solution in the presence of phenolphthalein. Calculate the percentage of HNO3 in the starting mixture.
A 1.000-g sample of a sweetening agent containing soluble Saccharin (MM=205.17g/mol) was analyzed using the Volhard method as follows: Step 1: Sample was dissolved in distilled water and treated with 10.0 mL of 0.05M AgNO3. Saccharin-Na + Ag+ → Saccharin-Ag (s) + Na+ Step 2: The solid, Saccharin-Ag (s), formed was filtered off and washed with water. The filtrate and washing were collected quantitatively. Step 3: Titration of the filtrate and washings required 4.6 mL of 0.04M KSCN. KSCN + Ag + → AgSCN (s) + K+ Calculate weight % saccharin in the sweetening agent sample. could you type it out, please
2. Using the procedure described in this module, a student determined the percent KHP in an impure sample of KHP. A 3.150-g sample of impure KHP required 41.50 mL of 0.1352M NaOH solution for titration. (a) Calculate the number of moles of NaOH required for the titration. (b) Calculate the number of moles of KHP present in the impure sample of KHP. (c) Calculate the number of grams of KHP present in the impure sample. (d) Calculate the percent of KHP in the impure sample, using Equation 8. Equation 8: percent KHP in the impure sample, % = ( mass of KHP in the sample,g/ mass of sample analyzed, g) (100%)
A sample of alfalfa meal weighing 2.0 g is analyzed by Kjeldahl method for the percentage of nitrogen. The liberated NH3 is caught in a solution of H3BO3, and 8.23 ml of HCl are required in the subsequent titration. A sample of pure (NH4)2SO4 (132.12) weighing 0.61 g is treated with excess NaOH and the liberated NH3 (17.04) is also caught in H3BO3. The resulting solution requires 20 ml of the acid for titration.

In the titration of 25.00 mL of a water sample, it took 20.590 mL of 3.150x 10−3 M EDTA solution to reach the endpoint. The total hardness is due to one or a combination of Ca2+, Mg2+, and Fe2+ in your sample. It is convenient to express this hardness as though it was entirely due to Ca2+. Making this assumption, determine the number of moles of Ca2+ present in the bottled water sample titrated. (enter your answer with 3 significant figures)
A mixture containing only KCl and NaBr is analyzed by the Mohr method. A 0.2125-g sample is dissolved in 25 mL of water and titrated to the Ag2CrO4 endpoint, requiring 25.63 mL of 0.1110 M AgNO3. A blank titration requires 1.15 mL of titrant to reach the same end point. Report the %w/w KCl and NaBr in the sample. KCl = 74.551 NaBr = 102.89
