(d) In potable water, the secondary maximum contaminant level (SMCLs are for contaminants that will not cause adverse health effects) for Mn2+ is 0.05mg/L. The concentration of Mn2+ in a sample of water entering a drinking water treatment works was measured at 0.1ppm. (i) What percentage of Mn2+ needs to be removed through treatment such that the water conforms to the SMCLs? The density of the effluent water can be assumed to be 1kg/L [3] (ii) The molar mass of Manganese (Mn) is 54.9g/mol. What is the molar concentration of Mn2+ in the water sample? [2]
