A concentration of toxic metals in plant tissue is often found by combusting the material in a furnace and then dissolving the ash in concentrated acid. A 0.5124-gram sample of leaves was combusted to ash and transferred to a 150-mL beaker. A 25-mL portion of concentrated HCl was added and the mixture was heated on a hot plate. Three 5-mL portions of concentration HCl were added over approximately 10 minutes with continued heating in between additions. The resulting mixture was cooled to room temperature and filtered into a 50-mL volumetric flask, which was brought to volume using distilled water and mixed well. From this stock solution, a 10-mL portion was pipetted into a clean 50-mL volumetric flask, brought to volume with distilled water, and mixed. This final solution was analyzed and found to contain 12.1 ppm lead. What are the mass percent of lead in the original plant tissue?

. The total cation content of natural water is often determined by exchanging the cations for hydrogen ions on an ion exchange resin. The cations are adsorbed to the resin which releases H+ (1:1 exchange) which can then be titrated with a base. A 25.0 mL sample of a natural water is diluted to 100 mL with distilled water and 2.0 g of a cation-exchange resin was added. After stirring, the mixture was filtered and the solid remaining on the filter paper was washed with three 15.0 mL portions of distilled water. The filtrate and washing required 15.3 mL of 0.0202 M NaOH to reach the equivalence pt. Calculate the number of moles of cation present in 1.00 L of sample.
