Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.

Question

6. A potential difference of 9 V is maintained across a
conductor in a circuit. If the conductor has a resistance
of 10 ohms, how many electrons flow through the
conductor's cross-section in 5 seconds?
