Explain the copper concentration of the solution

Reference no: EM13290847

A 1.25g sample of copper ore was dissolved in acid and diluted to 250.0 mL. A 20.00 mL portion was diluted to 50.00 mL. The copper concentration of this solution was 4.62 ppm. What is the weight percentage of copper in the ore? (correct significant figures).
