    Answer:

    2.43 * 10^(-13) C

    Explanation:

    The net charge of the system is given as the sum of the total charge of the electrons and the charge of the protons.

    Qnet = (Ne * Qe) + (Np * Qp)

    Ne = number of electrons = 6.16 * 10^6

    Np = number of protons = 7.68 * 10^6

    Charge of an electron = -1.602 * 10^(-19) C

    Charge of a proton = 1.602 * 10^(-19) C

    Qnet = (6.16 * 10^6 * -1.602 * 10^(-19)) + (7.68 * 10^6 * 1.602 * 10^(-19))

    Qnet = -9.87 * 10^(-13) + 12.30 * 10^(-13)

    Qnet = 2.43 * 10^(-13) C
