Answer:
0.00120 moles of electrons had traveled through the wire.
Explanation:
Amount current passed in 132 seconds = 0.880 A
Charge passed in 132 seconds = Q
[tex]Q=0.88 A\times 132 s=116. C[/tex]
Number of electrons = N
Magnitude of charge on an electron = q = [tex]1.602\times 10^{-19} C[/tex]
[tex]Q=N\times q[/tex]
[tex]N=\frac{116. C}{1.602\times 10^{-19} C}=7.25\times 10^{20} [/tex]
1 mole = [tex]N_A=6.022\times 10^{23}[/tex] ions/ particles/ atoms
The moles of electron in [tex]7.25\times 10^{20} [/tex] electrons:
[tex]=\frac{7.25\times 10^{20}}{6.022\times 10^{23}}=0.00120[/tex]
0.00120 moles of electrons had traveled through the wire.
