A calibration curve was pletted of Absorbance as function of Concentration of Cu2+ in units of M and the best fit through the line was found to be A=6.335Cu2+. A 21.30mL aliquot of the original unknown Cu2+ solution was diluted to a total volume of 82.4mL. If the diluted unknown Cu2+ solution had an absorbance of 0.484, then what was the concentration Cu2+ in the original, undiluted unknown in units of M? Report your answer to 4 places after the decimal point. Do not enter units. Type your answer... 2 points Calculate the equation of the best line through the following data set
