A single point calibration (2)
You have a standard solution of 1.677 M lead. You quantitatively dilute 5.00ml of this solution into a 100ml volumetric flask. AES analysis of this diluted solution finds a voltage of 102.3 mV. You then take an unknown solution of lead, and dilute 5.00ml to 50 ml in a volumetric flask, and record a signal of 321.2 mV. What is the concentration of lead in this unknown?
