An unknown sample of Cu2+ gave an absorbance of 0.262 in AA analysis. Then 1.00 ml of solution containing 100.0 ppm Cu2+ ws mixed with 95.0 ml of unknown and diluted to 100 ml in a volumetric flask, The absorbance of the new solution was 0.500.
a. Write an expression for the final concentration of Cu2+ after dilution.
b. Write the final concentration of added standard
c. Find the concentration of Cu2+ in the unknown
