A 1.058-g sample of a copper unknown was dissolved in water and diluted to a final volume of 100.0 mL. The sample was analyzed using a UV/VIS spectrophotometer and the absorbance was found to be 0.529. The calibration curve gave a best fit line of A = 8.58 M. Calculate the %(w/w) Cu in the sample. Give your answer to one place after the decimal. Do not enter units. A 1.058-g sample of a copper unknown was dissolved in water and diluted to a final volume of 100.0 mL.
