To determine the unknown concentration of a food dye in a serving of the orange drink, you will first prepare a standard (calibration) curve using solutions of the same dye at known concentrations. What does the slope of the standard (calibration) curve represent?
- The percent transmittance (%T) of the unknown dye solution
- The path length (b) of the cuvette
- The absorbance (A) of the unknown dye solution
- The molar extinction coefficient (ϵ) of the dye multiplied by the path length (b) of the cuvette
- The concentration (c) of the unknown dye solution the molar extinction coefficient (ϵ) of the dye
