concentration of a species‚ in this case (3). Where A is the measure of absorbance. Ԑ is the molar absorptivity‚ and is the constant of proportionality. And c is the concentration of the absorbing species‚ . When this information is graphed with absorbance on the y axis and at different points of concentration on the x axis‚ the best fit line equation will have a slope that is equal to Ԑ‚ giving us molar absorptivity (1). Then we can use the value of Ԑ to determine the concentration of [K2Cr2O7]
