How Many Electrons Pass Through The Wire In One Second?

The answer is 1.6 x 10^18 electrons per second.

The current through the wire is equal to the voltage across the resistor divided by the resistance of the resistor. In this case, we have 6 volts across the resistor and a resistance of 10 ohms, so we can calculate that there will be 6 volts / 10 ohms = 0.6 amps through the circuit.

In order to find out how many electrons pass through in one second, we need to multiply this current by charge (which is what an electron carries). The charge on an electron is 1.6 x 10^19 Coulombs (C), so if there are 0.6 amps flowing through our circuit then there are 1.6 x 10^19 C / second being carried by electrons moving through it.
