Question

An unknown was prepared with the concentration of 0.000630 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 1550.2 M–1 . The expected absorbance and %T values for the diluted aspirin solution prepared by the student is _______ and _________, respectively.

Answer 1

If you plot these as A vs C, and if it obeys Beer's Law, it gives a straight line passing through the origin with the slope of Absorbance/concn = 1550.2.
Thus A = 1550.2*0.000630 = ??
and A = log(100/%T)

Answer 2

0.98 is correct
but the second part is not right
