An unknown was prepared with the concentration of 0.0000890 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.

    I'm having a little trouble undersanding how an unknown is prepared AND you know the M. However, I think what you want to do is
    1750/M x 8.9 x 10^-5 M = absorbance
    Then A = log 1/T.
