Question

If 0.6mole of electrons flows through a wire in 50min. What are the total charge that passes through the wire

Answer 1

Explanation:

It is given that,

Number of mole of electrons, $n=0.6\ mole = 0.6 \times N_a$

$N_a$ is Avogadro's number

So, $n=0.6\times 6.023\times 10^{23}$

$n=3.61\times 10^{23}\ electrons$

Time, t = 50 min = 3000 seconds

Total charge is quantized. It is given by, q = ne

$q=3.61\times 10^{23}\times 1.6\times 10^{-19}=57760\ C$

Hence, the total charge that passes through the wire is calculated.
