The tetraethyl lead [Pb(C2H5)4] in a 25.00 mL sample of aviation gasoline was shaken with 15.00 mL of 0.02158 M I2. (Hint: one mole of I2 reacts with one mole of the tetraethyl lead). After the reaction was complete, the unused I2 was titrated with 4.86 mL of 0.02944 M thiosulfate solution. Calculate the weight in milligrams of [Pb(C2H5)4] (MW = 323.4 g/mol) in each liter of gasoline. Assign an oxidation number to the element specified in the compound or ion below: N:N2O2 N:NH4+
