145. Solving a chemistry problem

66. When determining the copper in the electrolyte by the comparison method, the analyzed solution was diluted 100 times. The atomic absorption of this solution at 324.8 nm is equal to 24.0 units of the instrument scale.
A standard solution of copper with a concentration of 100.00 µg Cu in 1.00 ml has an atomic absorption of 32.0 units. Determine the concentration (g / l) of copper in the electrolyte.
