A group of students decided to use AAS to analyze three different brands of iron tablets to determine their content. They placed a tablet in a 100 mL beaker with 6 mol/L HCl and covered it with a watch glass and heated slowly for 15 min. They then filtered the solution into a 250 mL volumetric flask and topped it up to mark with distilled water. They determined the absorbance of the sample and repeated the same process for the other two samples Sample A: Absrobance =0.85 concentration of iron in solution = 4.7 ppm Sample B Absorbance = 0.8 Concentration of iron in solution = 0.6 ppm Calculate the concentration of iron in the tablet itself. 2. Relevant equations Equations: Molarity = n/v 3. The attempt at a solution I have no clue what to do. If only somebody can point me in the right direction I would be very grateful.
