The toxicity of DDT (C14H9CI5) led to a ban on its use in the United States in 1972. Determinations of DDT concentrations in groundwater samples from Pennsylvania between 1969 and 1971 yielded the following results: Location Sample Size Mass of DDT Orchard 255 mL 0.0290 mg Residential 1.79 L 0.0360 mg Residential 53.5 mL 0.580 mg after a storm Express these concentrations in millimoles per liter. 4th attempt Part 1 l See Periodic Table O See Hint Orchard -4 3.2082 х 10 mmol/L + Part 2 Residential x 10 -5 mmol/L - 3.05823 Part 3 Residential after a storm 0345 mmol/L
