Ethanal is made by the palladium-catalysed oxidation of ethene in aqueous medium, overall $2 C X_{2} H X_{4} + O X_{2} 2 CH X_{3} CHO$ . The atom economy of this process is

All atoms of ethene and oxygen end up in ethanal, so the mass of desired product equals the mass of reactants:

2 \times 44 = 88 = 56 + 32

. The atom economy is 100%.
