The tetraethyl lead Pb(C2H5)4 in a25.00 mL sample of aviation gasoline was shaken with 15.00 mL of0.02177 M I2. (Hint: one mole of I2 reactswith one mole of the tetraethyl lead). After the reaction was complete, the unused I2 was titrated with 6.94 mL of0.02607 M thiosulfate solution. Calculate the weight of Pb(C2H5)4 (MW = 323.4 g/mol) in each liter of gasoline.
