A simple AA spectrometer is used to analyze copper in water samples. The blank provides a reading of 94.6, a 0.200 ppm Cu(II) solution gives a reading of 53.8, a sample gives a reading of 46.4 and the instrument reads 6.8 with the light beam blocked. What is the concentration of Cu(II) in the sample? Assume Beer's Law holds. A simple AA spectrometer is used to analyze copper in water samples.
