Question

A strong lightning bolt transfers an electric charge of about 16 C to Earth (or vice versa). How many electrons are transferred? Avogadro’s number is 6.022 × 1023 /mol, and the elemental charge is 1.602 × 10−19 C.

Answer 1

Answer:

Number of electrons, $n=9.98\times 10^{19}$

Explanation:

A strong lightning bolt transfers an electric charge of about 16 C to Earth, q = 16 C

We need to find the number of electrons that transferred. Let there are n electrons transferred. It is given by using quantization of electric charge as :

q = ne

$n=\dfrac{q}{e}$

e is elemental charge

$n=\dfrac{16}{1.602\times 10^{-19}}$

$n=9.98\times 10^{19}$

So, there are $9.98\times 10^{19}$ electrons that gets transferred. Hence, this is the required solution.
