An unknown sample of Cd2+ gave an absorbance reading of 0.259 in an atomic absorbtionan analysis. then 0.5 mL of solution containing 4 ppm of CD2+ was mixed with 50.0 mLof the unknown sample. this solution gave an absorbance reading of 0.368.

(A) denoting the initial, unknown concentration CD2+, write an equation to calculate the final concentration , CD2+ considering the dilution factor, units are ppm.

(B) In a similar manner, write the final concentration of added Cd2+ standard, designated as [S] known.

(C) Find the concentration of Cd2+ in the unknown.
