The toxicity of DDT (C14H9Cl5) 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 253 mL 0.0310 mg Residential 1.77 L 0.0350 mg Residential after a storm 51.5 mL 0.570 mg Express these concentrations in millimoles per liter. Orchard= ___mmol/l Residental=___ mmol/l Residential after a storm=___ mmol/L
