Problem
Three solutions—P, Q, and R—of the same transition-metal complex are analyzed at a fixed wavelength in identical 1.00 cm cuvettes. The measured absorbances are 0.38 for P, 0.26 for Q, and 0.52 for R. Which ranking correctly orders their concentrations from greatest to least?
(a) Q>P>R
(b) P>R>Q
(c) R>P>Q
(d) P>Q>R
