    Answer:

    Approximately 5 x 10^18 electrons are delivered to the smart phone charger.

    Explanation:

    The electric current in a circuit is the flow of charges through a circuit with time.

    The charges through the circuit are due to the electrons that flow through the circuit.

    An individual electrons has a charge of -1.60 x 10^-19 C on it.

    If the current through the circuit is -0.75 C/s, then the number of electrons that are delivered is gotten by dividing the charge per second by the charge on an electron.

    ==> -0.75/(-1.60 x 10^-19) = 4.67 x 10^18 electrons ≅ 5 x 10^18 electrons are delivered to the smart phone charger.
