Beer's Law states that the adsorbance of a solution is directly proportional to its concentration. Therefore plot a graph of adsorbance verses concentration of a known standard. this will produce a staight line. Then find the equation of the straight line and use this equation, with a known value of % T (% Transmitted), you can calculate the concentration of the unknown solutions.
Adsorbance = 2-[log(%T)]

i'm assuming that the calibration line is linear by way of 2.2 M concentration. A = elc 0.88 = (el)(2.2 M) el = 0.40 So your calibration line has the equation y = 0.40x, or A = 0.40c If the absorbance of the diluted answer is 0.60, then 0.60 = 0.40c c = a million.5 M

Beer's law? hahah what kind of law is that. I wish chemistry could be this funny.
