An analyst weighed 0.25045 g of the Buffalo River Sediment reference material. (RM # 8704) to determine Pb levels. The material was digested in an acid medium to Bring it to a solution which was made up to the 30.2450 mL mark with distilled water. If the Pb concentration in the control certificate of analysis is (150 ± 17) mg / kg, and the analyst recovered 95%, what was the concentration of Pb in the solution?
