The iron content of a municipal water supply was determined by an atomic absorption procedure. The absorbance of the water, after a ten-fold dilution was 0.500 at 248.3 nm. A standard solution prepared by dissolving 0.1500 g of pure iron wire in acid, diluting to 1.00 L and then making a 25-fold dilution, had an absorbance of 0.750. Calculate the ppm Fe in the water sample.
