Solution A initial:
Absorbance = kc
Substitute A and c, calculate k.
Diluted solution:
new concn = 0.0283 x (6.57/100)
Substitute k and new c, calculate Absorbance.
Solution A, while in a 1.0 cm cell, has an absorbance of 0.390 and a [Cu2+] = 0.0283 M. Then, 6.57 mL of solution A is diluted with pure water to 100.0 mL. What is the absorbance of this diluted solution?
I tried but I still don't get it. Can anyone please help! :( Thanks!
