Calculating Radionuclide (243 Am3+) in a solution

  1. Apr 28, 2017 #1
    1. The problem statement, all variables and given/known data
    There is an UV-Visible experiment on 243Am3+ in 1 M HClO4 with a 1 cm path length
    cuvette and a total volume of 2.5 mL. The absorbance near 500 nm is 0.35. What is the solution concentration of Am

    2. Relevant equations
    A = ebC

    A = absorbance
    b = path length
    C = concentration
    e = molar absorptivity

    The attempt at a solution
    I first calculated the molar absorptivity using the absorbance, concentration of 1M HCLO4 and the path length and right off the bat, I knew that this method is wrong (e=0.35, same as the abs reading). I then use the A=ebC equation, but then again this method is wrong because it gave me the same concentration of Am to the concentration of HCLO4. Please help guiding me through this problem.
