The Safe Drinking Water Act (ADWA) sets a limit for mercury- a toxin to the central nervous system- at 0.0020 ppm by mass. Water suppliers must periodically test their water to ensure that mercury levels do not exceed this limit. Suppose water becomes contaminated with mercury at twice the legal limit (0.0040 ppm). How much of this water (L) would a person have to consume to ingest 50.0 mg of Hg? (Assume a density of 1.0 g/mL)
