Hint: As we know $Q$ coulomb ($C$) charge contains$n$times the charge of electron, electrons, and can be expressed as $Q = ne$, where $e$is the charge of electron and$n$is the number of electron. Here, we have to find the number of electron contained in $1\,C$

As we know $Q$ coulomb ($C$) charge contains n times the charge of electron, electrons, and can be expressed as $Q = ne$, where $e$is the charge of electron ($i.e.$ $1.6 \times {10^{ - 19}}C$)
Now, according we have to find the number of electrons in 1 coulomb charge
$\Rightarrow$$Q = ne$
On putting the values of $Q$and $e$we get,
$\Rightarrow$$1 = n \times 1.6 \times {10^{ - 19}}$
$\Rightarrow$$n = 6.25 \times {10^{18}}$

Hence, the number of electrons contained in $1\,C$charge is $6.25 \times {10^{18}}$ that is option (D)

A coulomb is an enormous charge – two $1\,C$charges that are $1\,\,m$ apart exert a force of $9 \times {10^9}Newton(N)$. That's over two million tonnes, 720 times as much as the thrust of a space shuttle solid rocket booster during lift-off.
