In a similar experiment you did for Atomic Absorption Spectroscopy (AAS), AAS was used to analyse Pbin river water sample and therefore a calibration curve of Pbt was made by using diluted standard solutions of Pbt and AAS analysis. The calibration curve for the analysis is shown below. Considering the Pbt unknown sample gave an intensity of 16.5, what is the concentration in the unknown sample (1 Mark) 25 20 15 Emission Intensity 10 5 y = 2.0714x + 0.4762 R? = 0.9969 IS 10 PbConcentration, mg/L O a. 7.74 M b. 7.74 mg/L 0 C. 34.65 mg/L O d. 77.4 mg/L
