    3.75 x 10^10

    Explanation:

    charge, q = 6 nC = 6 x 10^-9 C

    Charge of one electron, e = 1.6 x 10^-19 C

    Number of electrons removed = total charge / charge of one electron

    n = (6 x 10^-9) / (1.6 x 10^-19)

    n = 3.75 x 10^10

    Thus, the number of electrons removed is 3.75 x 10^10.

    n = 3.75 x 10¹⁰ electrons.

    Explanation:

    given,

    Charge on the glass rod = 6 n C

    In the given question the electron is removed because proton never moves.

    We know

    Charge of 1 electron = 1.6 x 10⁻¹⁹ C

    x number of electron have charge = 6 x 10⁻⁹ C

    now,

    n * 1.6 x 10⁻¹⁹ C = 6 x 10⁻⁹ C

    where n is the number of electron

    n = 3.75 x 10¹⁰ electrons.

    number of electron moved is equal to n = 3.75 x 10¹⁰ electrons.
