When a 10.00 ml sample (density 1.00 g/ml) containing fluoride ion was added to 25.00 ml of zrl2, the absorbance due to the complex decreased from 0.800 to 0.379 in a 1.00 cm cell. if the molar absorptivity of zrl2 is 2.17 x 105 , calculate the concentration (in parts per million) of f- in the sample. hint: do not forget about the dilution!

(Probably) Mountain soils because they are in cold temperatures and there is chemical weathering and erosion causing the soil to have a more difficult environment to form in.
