A 14 mg sample of lead (Pb) was consumed orally and completely solublized by an average person's gut such that all the lead went into the blood stream. What is the minimum (exact) volume of a 0.0195 M solution of EDTA needed to neutralize the lead contamination to the human? (Average Person's blood volume is 4.7L, EDTA binds lead in a 1-to-1 ratio)
-
(14 mg Pb) / (207.2100 g Pb/mol) x (1/1) / (0.0195 mol/L) = 3.5 mL
