The molar mass of allyl chloride is 76.53 g/mole. However, the mass spectrum of allyl chloride shows M" at m/e 76 and relative intensity of 40%, an M+2)* at m/e 78 and relative intensity 14%. Select the correct explanation. a. The M* and (M-2)* peaks as well as the molar mass given are consistent with the relative natural abundance of chloriine isotopes. b. Carbon-14 in the sample gives rise to the smaller (M+2)* peak. Mass spectrometry can only show integer masses. C. Allyl chloride molecular ion with Me=78 loses H2 after ionization to give an ion with m/e = 76. d.

Suppose that s = 0.28 nA instead of 0.56 nA, but yblank is still 1.26 nA. Find the signal detection limit, the minimum detectable concentration, and the concentration of analyte in a sample with a signal of 7.0 nA.
6. A sample of an alum was analysed by atomic spectroscopy and gravimetrically to determine its structure. A 0.1000 g of the sample when treated with BaCl₂ produced 0.0984 g of a white solid after drying to constant weight. Another 0.1000 g sample of the alum when heated at 105°C for several hours produced a weight loss of 0.04558 g while the % of K in the sample was determined by atomic spectroscopy to be 8.240%. Use these results to work out a formula for the alum. [M,/ g mole¹: K 39.10; Al 26.98; BaSO, 233.39; SO² 96.06; H₂O 18.0148]
Exactly 10.00-mL aliquots of a solution containing phenobarbital were measured into 50.00-mL volumetric flasks and made basic with KOH. The following volumes of a standard solution of phenobarbital containing 2.000μg/mL of phenobarbital were then introduced into each flask and the mixture was diluted to volume: 0.000, 0.500, 1.00, 1.50, 2.00 mL.

Sally obtains a standard calibration curve for their assigned food dye by plotting absorbance versus concentration (in M) of known solutions and finds the following slope and intercept: y = 1.646x + 0.026 Note: Copying and/or posting this or other questions without the express written permission from Dr. Burke and the Department of Chemistry & Biochemistry at the University of Delaware is a violation of intellectual property copyright law. Sally finds that her original Kool-aid sample is too concentrated, so they dilute it by transferring 13.00 mL of the original Kool-aid sample into a new container and diluting to a total volume of 37.00 mL. If the absorbance of the dilute Kool-aid sample at the appropriate wavelength for their assigned dye is 0.950, determine the concentration (in M) of the assigned food dye in the original Kool-aid sample. Report your answer with three places after the decimal.
