The herbicide dichlobenil (2,6-dichlorobenzonitrile, C7H3Cl2N) has a solubility of 18.0 mg/L by mass in water at 20 degrees Celcius. The herbicide disintegrates with a half-life (first order) of 1.00 year. Suppose that 309 kg of dichlobenil is applied in the fields surrounding a 7.50-acre pond having an average depth of 3.00 ft. Suppose further that half of the dichlobenil permeates into the pond and that this happens within a few days. Assume that the density of the pond water is 1.00 g/mL. After a few days, what will be the concentration of dichlobenil in the pond? The following conversion factors will be helpful: 1 acre=43,560ft2 1ft=12in 1in=2.54cm 1cm3=1mL 1ft3=28,317cm3
