4. (14 points) A soil sample (4.00 g) is digested and analyzed for Cd by atomic absorption analysis. The digestion results in 25.0 mL of extract. Because there is concern of matrix effects, standard addition is used. A portion of the extract is analyzed directly by AA and gives an absorbance of 0.211. Another 10.0 mL portion of the extract is spiked with 50.0 ug of Cd (ignore any added volume from Cd spiking) and gives an absorbance of 0.539. a) Calculate the Cd concentration in the (unspiked) extract (in ug/mL).

Given the diameter of the asteroid to be (8.50x10^0) km and the density of the asteroid to be (2.1100x10^0) g/cm, calculate the total mass of the asteroid. Remember to round your answer to the correct number of significant figures Note: The answer is assumed to be reduced to the highest power possible.(This means that everything is in scientific notation) When entering units for the answer, use the symbol for the unit, and if the unit has an exponent, enter the exponent as a carat(^). For example, grams would be "g" and, the unit grams per centimeter squared would look like, g/cm^2. Note: Your answer is assumed to be reduced to the highest power possible.

From the study with UV-Vis spectroscopy, four samples of solutions with different known concentrations of atrazine were analyzed, using a 1 cm optical path cuvette at 220 nm. The analytical curve (calibration curve) with absorbance values (y-axis) per atrazine concentration (x-axis) provided a straight line with the following parameters: linear coefficient = 0 and slope = 760. assumptions of the Lambert-Beer Law, evaluate the following statements: I. The molar absorptivity coefficient (E), under the described experimental conditions, cannot be determined. II. A sample of a solution containing atrazine with an absorbance of 0.2 will show a concentration of 2.6x10-4 mol/L. III. Atrazine concentrations could be determined due to absorption taking place in the visible region. IV. The change in absorbance as a function of the analyte concentration is directly related to the absorptivity coefficient of atrazine and the length of the optical path of the cuvette. It is correct only what is…

A series of solutions of known Na+ content were used to prepare a calibration curve for flame emission analysis. Using data from the linear portion of the calibration curve gave slope = 0.125 emission units/ppm Na, and intercept or %3D constant = 0.012. A 355-mL cane of juice was analyzed for its Na content by flame emission spectroscopy at the same time as the standard curve was determined. A 10.00-mL aliquot of juice was brought to a total volume of 100.00 mL with Na- free water. The diluted juice solution gave an emission intensity of 0.632 units. What was the Na ppm concentration in the cane of juice? If a person consumed the entire can of juice, how many mg Na+ would be ingested?
