Lead can be obtained by heating its oxide with carbon. The balanced equation for the reaction is 2PbO + C → 2Pb + CO2 .Calculate the atom economy for the production of lead in this reaction. (relative atomic masses: C = 12, O = 16, Pb = 207 relative formula masses: PbO = 223, CO2 = 44). Give your answer to two significant figures – 9038

1. (2×223)+12=458
   2×207=414
   (414/458)×100=90.39
   =90%
