Question 1 a. Explain the origin of optical atomic absorption spectra by referring to atomic sodium. Draw a sketch to support your explanation b. A vaccine sample solution was subjected to spectroscopy study. About 8 X 105 M solution has an absorption of 0.60, as measured in a 2.0 cm cell at a wavelength of 485 nm. Calculate the molar absorptivity of KMNO c. Use the Table to answer the questions below Concentration (M) Absorbances 0.20 0.36 0.40 0.50 0.60 0.65 0.80 0.75 Plot the graph and attach your plot. Use the table to answer the following question i. If 1.1 cm cell was used. Calculate the molar absorptivity of Cr(III). ii. What is the concentration of a compound with absorbance 0.60, if 2 cm cell is used.
