You are in the lab preparing copper solutions for the MICRO lab this week. You measure 0.1035 (±0.0001) g of copper metal and dissolve it in a few mLs of concentrated nitric acid. This solution is diluted to the mark with water in a 50.00 (±0.05) mL volumetric flask. You withdraw a 5.00 (±0.01) mL aliquot with a volumetric pipet and deliver it to a 100.00 (±0.08) mL volumetric flask. After dilution to the mark with water, calculate the concentration and the absolute error in a solution of copper in ppm (assume ppm = 1 µg/g = 1 µg/mL = 1 mg/L).
