A Solid contains `5 xx 10^(21)` number of atoms. If an electron is removed from each of 0.01% of number of atoms, find the charge gained by this solid?

Explanation

The solid gains positive charge hence Q= ne Where `n = (5 xx 10^(21) xx (0.01)/(100)) = 5 xx 10^(17)`
`therefore Q= 5 xx 10^(17) xx 1.6 xx 10^(-19) therefore Q = +0.08C`
