The maximum contaminant level (MCL) set by the EPA of antimony in drinking water is 0.0060mg/L. Convert the MCL of antimony from milligrams per liter to parts per billion (ppb). converted MCL of antimony: ppb A farmer recently dug a new well for his property. He sends a 10.0mL sample of the well water to the EPA to be tested for the presence of antimony. What is the maximum amount of Sb (in g ) that can be present in this 10.0mL sample based on its MCL? maximum amount of Sb : Suppose the farmer rethinks his plan and digs a new well on the other side of his property. He sends in a new 10.0mL sample. After testing, the EPA determines that the sample of water contains 0.00125g/mLSb
