A soil contaminated with lead, weighing 1.2354mg was dissolved in a 25mL volumetric flask and diluted to the mark. The solution was analyzed but proved to be too concentrated, so a further dilution was made by taking a 10mL aliquot, placing it into a 50mL volumetric flask and diluting to the mark. This unknown was then analyzed for lead using a 10.0cm cell. The results are compiled into the table below: 1. Find the molar absorptivity (M.W. 207.2g/mol ) 2. Find the concentration (ug/mL) of lead in the 50mL volumetric flask 3. Find the concentration (\% w/w ) of lead in the original soil sample
