A sample of an unknown peptide was divided into two aliquots. One aliquot was treated with trypsin; the other was treated with cyanogen bromide. Given the following sequences (N-terminal to Crterminal) of the resulting fragments, deduce the sequence of the original peptide. | Numerade

35 ml aliquot was obtained from a mixture of 98 unknown solution if half the sample is diluted to 100ml what will be the final concentration 10926

SOLVED: A sample contains a concentration of (1.37 * 0.06) x 10-6 M: An aliquot of this sample is measured with a 10.00 0.02 mL pipet and diluted in a 50.00 0.05 mL volumetric flask: Calculate the final concentration, including uncertainty:

SOLVED: A) Chloride in a brine solution is determined by the Volhard method. An aliquot of 10.00 mL is treated with 15.00 mL of 0.1182 M AgNO3 solution. The excess silver is titrated with a standard 0.101 M KSCN solution, consuming 2.38 mL to reach the red Fe(SCN)2 endpoint. Calculate the chloride concentration in the brine solution in g/L.B) A hydroxide solution is standardized by titrating 0.8592 g of primary standard potassium hydrogen phthalate to a phenolphthalein endpoint, consuming 32.67

SOLVED: Chloride is determined in a brine solution by the Volhard method. A 10.00 mL aliquot is treated with 15.00 mL of 0.1182 M AgNO3 solution. The excess of silver is titrated with a standard solution of KSCN 0.101 M, with a consumption of 2.38 mL to reach the end point of red Fe(SCN)2 . Calculate the chloride concentration in the brine solution in g/L. Express your result to two decimal places: PMCl- 35.5 g/mol; PMAgNO3 = 170 g/mol.
