In a similar experiment you did for Atomic Absorption Spectroscopy (AAS), AAS was used to analyse Pbt in river water sample and therefore a calibration curve of Pbt was made by using diluted standard solutions of Pb* and AAS analysis. The calibration curve for the analysis is shown below. Considering the Pb unknown sample gave an intensity of 16.5, what is the concentration in the unknown sample (1 Mark) 25 20 Emission Intensity 2,0714x +0,4762 R0.9969 Pb Concentration, mg/L O a. 34.65 mg/L Ob 7.74 mg/L Oc 77.4 mg/L od 7.74 M
