3) The solution taken from a factory waste sample to prepare an internal standard contains Pb + 2 and Ag + 2, and the analysis peaks were determined as 298 mAU and 324 mAU. To analyze the unknown, a solution containing 0.150 M, 50.0 mL of Ag + 2 is put into the unknown liquid and completed to 100.0 mL. When the peaks are measured again, 670 mAU and 856 mAU signals are read from the samples. is the concentration of Pb + 2 in the unknown liquid?
