A solution with a known concentration equal to 3.4 mM gave an absorbance reading of 0.820 in a spectrophotometer. Assuming that there is a linear relationship between concentration and absorbance up to a concentration of 4.0 mM, what would the absorbance reading be for a solution with a concentration 2.2 mM?
