At 510 nm, the red dye at 3.0 ppm has an absorbance of 0.183 in a cell of path length 1.00 cm. Therefore the absorbtivity coefficient (a) is: a red,510 = 0.183/(3.0ppm x 1.00 cm) = 0.061 ppm-1 cm-1. These values may be used to calculate the concentrations of these red and blue dyes in other mixtures:
