Answer:
[tex]n=3.0\times 10^{13}[/tex]
Explanation:
Charge on 1 electron = [tex]-1.6\times 10^{-19}\ C[/tex]
The expression for charge is:-
[tex]Charge=n\times q_e[/tex]
Given that:- Charge = [tex]-4.8\times 10^{-6}\ C[/tex]
[tex]-4.8\times 10^{-6}=n\times (-1.6\times 10^{-19})[/tex]
[tex]n=\frac{4.8\times 10^{-6}}{1.6\times 10^{-19}}=3.0\times 10^{13}[/tex]
Total number of electrons, n = [tex]3.0\times 10^{13}[/tex]
The total number of electrons the charge represent is 3.0 × 10¹³
Calculating number of electrons
From the question, we are to calculate the total number of electrons
Using the formula,
Q = ne
Where Q is the total charge
n is the number of electrons
and e is the charge of an electron
From the given information,
q = - 4.8 × 10⁻⁶ C
(NOTE: The negative sign indicates the type of charge)
e = 1.6 × 10⁻¹⁹ C
Then,
4.8 × 10⁻⁶ = n × 1.6 × 10⁻¹⁹
n = [tex]\frac{4.8 \times 10^{-6} }{1.6 \times 10^{-19} }[/tex]
n = 3.0 × 10¹³
Hence, the total number of electrons the charge represent is 3.0 × 10¹³
