Question

How many electrons were gained or lost by a 6.8 milliC charge?

Answer 1

Answer:
`4.25* 10^(16)`

Step-by-step explanation:

Let
`e` be the charge of each electron in coloumbs.

Let the given charge be
`x` in coloumbs.

The number of electrons lost or gained by a
`x`
`C` is
`(x)/(e)`.

As we know,the charge of electron is a constant and is equal to
`1.6* 10^(-19)C`

So,
`e=1.6* 10^(-19)C`

Given,
`x=6.8* 10^(-3)C`

The number of electrons lost or gained by a
`6.8milli`
`C` is
`(6.8* 10^(-3))/(1.6* 10^(-19))`=
`4.25* 10^(16)`
