A beam of light with an irradiance of Po passes through a solution of a substance that can absorb some of the light. The pathlength of the solution is b cm, and the molar concentration of the substance is c M. The irradiance of the emerging light is P. Absorbance (A), transmittance (T), and molar absorptivity (e) are quantities calculated from these values. Identify the expression used for calculating each of these three quantities. = 11 Po P P Po = P₁ - P = log (P) = log (Po-P) = log = log Po P = Abc A bc bc A Answer Bank molar absorbtivity (e) transmittance (T) absorbance (A)
