A chemistry student prepares a standard calibration curve in a 1-cm-long cuvette by measuring the absorbance of several different concentrations of Cu2+. The concentration data in molarity were plotted on the x-axis against absorbance on the y-axis. The line of best fit through these data had a slope of 6.4 10'. An unknown solution of Cu2+ was measured and its absorbance was determined to be 0.74, what is the concentration of this unknown solution? a. 0.74 M b. 1.2 x 10 M C. 8.6 x 10 M d. o 6.4 10 M e. 4.7 x 10
