Mass and speed of (current) electrons

[Bjarne]

If a direct current (100 Volt) and (5 Amp.) is supplying a (500 Watt) bulb.
How many electrons (how much mass) are moving and how fast?

[Astronuc]

Students are required to show effort and work.

Current is related to charge transfer. 1 Amp = 1 Coulomb/s, and one knows the charge per coulomb.

I am not a student, but do just need the result.

PS !
The resistance in the wire we can assume to be zero.
