a solution of an analyte is placed in a 1.00 sample cell and has an absorbance of 0.228 when measured at a wavelength of 490 nm.its molar absorptivity is 676. what is the concentration of the analyte of l/(mol cm)
Homework Answers
A= ECl
E=molar absorptivity is 676
C=concentration of the analyte of l/(mol cm)
l= path lenth of sample cell = 1.00 cm
thus absorbance A = 676 X 1 X 1 = 676
