A Solid contains `5 xx10^(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 ? 

Text Solution

Verified by Experts

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