A solution of compound A in water exhibits an absorbance of 0.526 in a 1.000 cm cuvette at 473 nm light, for which ɛ=1500 (M*cm). The water alone (without compound A) is not entirely pure and had an absorbance of 0.011. Find the concentration of A in ppm, given A has a molecular weight of 257 g/mol.

As part of an investigation on Pb in biological ecosystems, some grasses that grew along the road and were exposed to emissions from motor gasoline were collected. 6.2501 g of grass were calcined to destroy all organic matter, the inorganic residue was properly treated and finally made up to 100 mL. An aliquot of 50 mL of this solution was read in an atomic absorption spectrophotometer registering an absorbance of 0.1250; then 0.10 mL of a standard solution of 55 µg of Pb / mL were added to the other 50 mL, with this fortified sample, another absorbance measurement was made, which was 0.1798. Calculate the µg of Pb / g of grass
