Homework Help: chemistry- absorbance & transmittance

Posted by christine on Friday, February 16, 2007 at 1:00pm.

An unknown was prepared with the concentration of 0.000120 M. A Beer's Law plot was prepared using the absorbance values from standard solutions of ASA and a line drawn through all the points passed through the origin with a slope of 1750.0 M–1. The expected absorbance and %T values for the diluted aspirin solution prepared by the student is ?
and ? , respectively.

A = 1750/mol x M of th soln.
solve for T from log 1/T = A.

Check my thinking.
