A joule is the work done by applying 1 watt of power for 1 second (J = W x Time in seconds).

1 Watt is 1 Amp at 1 Volt potential (W = Amps x Volts).

1 Amp is 1 coulomb of electrons flowing in a second.

1 coulomb is 6 241 509 629 152 650 000 electrons.

Thus it would appear that there are 6,241,509,629,152,650,000 electrons in a joule, except that 1 Joule could be 2 watts for half a second (or 4 W for 0.25 seconds).

Also 1 Watt could be 2 Amps and half a volt, or .01 Amps at 100 Volts!

The question has no one answer, it has an infinity of possible answers unless more parameters are dictated.
