Type answer: ВАCK Question 8 of 8 REVIEW A «tv A O Absorbance at 542 nmarrow_forwardConsider the analysis of a sample of iron using atomic absorbance spectroscopy. Which of the following statements are true? Select all that apply. The iron sample is aspirated into the flame, where the solvent evaporates and the iron analyte is atomized. The hollow-cathode lamp for iron emits wavelengths of light unique for iron. A detector measures the amount of light generated by the flame and not absorbed by iron. The iron atoms in the flame absorb some of the light emitted from the hollow-cathode lamp. The flame replaces the cuvet of conventional spectrometers and the flame pathlength is typically 10 cm.arrow_forwardQuestion 25 Using the given data above, determine the following information: What is the concentration of Jerry in the solution ? 497 mM 393 mM 468 mM O 366 mMarrow_forward
