Question

calculate the number of electron consisting one coulomb of charge ans

Answer 1

Hey.

Charge on an electron,

$e \: = 1.6 \times {10}^{ - 19} \: coulombs$

So, no. of electrons constituting 1 Coulombs charge is

$\frac{1}{1.6 \times {10}^{ - 19} } = 0.625 \times {10}^{ 19} \\ \\ = \: 6.25 \times {10}^{18}$


So, a total of 6.25× 10^18 electrons together will constitute 1 coulombs of charge.

Thanks.

Answer 2

Given that

Charge (Q) = 1 C

Electron (e) = 1.6× 10^-19

Number of electron (n) = ?

Q= ne

1 C = n × 1.6×10^-19 C

n = 1/(1.6×10^-19)

n = 6.25 × 10^18 electron
