Question 15 6 Points (1) A drug with a molecular mass of 292.16 was dissolved in a 5.00 me volumetric flask A 1.00 m aliquot was withdrawn placed in 10.00 ml volumetric fask, and diluted to the mark. The absorbance at 340 nm was 0.427 in a 1.00 cm cuvette. The molar absorptvity for this compound at 340 nm is 6730 mm Calculate the concentration of compound in the cuvette What will be the absorbance if the path length was decreased to 0.50 cm? 12) The solubility product values Ksp for three silver halides are given blow. Agor-52x10.AC-18x 10 Agio, -3.0 x 10 in perception titration between these halide solutions and AgNO) solution which halide give the sharpestend point and Why?
