A modern chealting agent used for this purpose is succimer (C4H6O4S2). Suppose you are trying to determine the appropriate dose for succimer treatment of lead poisoning. Assume that patient blood lead levels are 0.580mg/l, that total blood volume is 5.2L and that 1 mol of succimer binds 1 mol of lead. what minimum mass of succimer in miligrams is needed to bind all of the lead in a patients bloodstream?
