The molarity of a Cu²⁺ solution is to be determined from its absorbance, measured under the same conditions as those used to prepare this calibration curve. What will be the percent uncertainty in the concentration of a 0.050 M solution if the uncertainty in the absorbance reading is ±0.01 absorbance units?
