A 0.5145-g sample of a water-soluble fertilizer was dissolved and analyzed for nitrogen using the Kjeldahl method. After digestion, the distilled ammonia was collected in 100 mL of 0.1334 M boric acid. This solution required 29.38 mL of 0.202 M HCl for titration to the methyl red end point. Calculate the % N (AW =14 g/mol) in the fertilizer. Type the numerical answer only.
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 sample contains MgCl2 (95.211 g/mol) and KCl (74.551 g/mol). A 6.6933-g sample was dissolved in enough H2O to make 250.0-mL solution. A 50.00-mL aliquot was treated with AgNO3 to precipitate the chlorides and after proper collection and drying gave a precipitate weighing 1.9620-g.
