The concentration of a dilute aspirin solution is 0.000529 m. standard solutions of this compound were used to prepare a beer\'s law plot which gives a slope of 1550.7 m-1. what is the expected absorbance value for the aspirin solution?

From Beer-Lambert's law' A = ECl Since the slope is 1550.7 thus A = 1550.7* 0.000529 M = 0.8203203 Since A = Log (Io/I) and T% = I/Io * 100% Io/I = AntiLog(A) and hence T% = { 1/ AntiLog (A) } *100% T%={1/AntiLog 0.8203203)*100% T%=0.8601654108*100% T%= .860
