- A 1.50 g sample of coniine, the toxic extract of poison hemlock, was dissolved in 10.0mL of ethanol and placed in a sample cell with a 5.00 cm pathlength. The observedrotation at the sodium D line was +1.21°. Calculate [α]D for coniine.A stock solution of alcohol dehydrogenase (ADH) has been diluted 1 in 10 and the absorbance reading at 280 nm of this diluted solution is 0.04. Given that the absorption coefficient for ADH at 280 nm is e mg/ml = 1.6 and that you require to do 30 assays in triplicate, each assay using 2 ug of enzyme, how many ul of the stock ADH do you need to do the experiment?A 5.00-mL sample of blood was treated with trichloroacetic acid to precipitate proteins. After centrifugation, the resulting solution was brought to pH 3 and extracted with two 5-mL portions of methyl isobutyl ketone containing the lead-complexing agent APCD. The extract was aspirated directly into an air/acetylene flame and yielded an absorbance of 0.527 at 283.3 nm. Five-milliliter aliquots of standard solutions containing 0.400 and 0.600 ppm of lead were treated in the same way and yielded absorbances of 0.396 and 0.599. Find the concentration of lead in the sample in ppm assuming that Beer’s law is followed.
