A student dissolves a Jefferson nickel to make \( 100.00 mL \) of solution in a volumetric flask. The student takes a \( 5.00 mL \) aliquot of the first solution and dilutes it to make \( 100.00 mL \) of a second solution. The student places a sample of the second solution in a cuvette for analysis using spectrophotometry.
The molarity of the copper solution in the cuvette was determined by spectrophotometric analysis to be \( 2.90 \times 10^{-2} M Cu \). Calculate the mass of copper in the Jefferson nickel used to make the first solution.
Use the diagram to help visualize the dilution process.
