In `1 g` of a solid, there are `5xx10^(21)` atoms. If one electrons is removed from each of 0.01% atoms of the solid, find the charge gained by the solid (given that electronic charge is `1.6xx10^(19)C` ).

Options

A. `+0.08C`
B. `+0.8C`
C. `-0.08C`
D. `-0.8C`

Answer

A

Explanation

Number of atom in 1 g of a solid
`n=(0.01)/(100)xx5xx10^(21)=5xx10^(17)`
`q=-n =-5xx10^(-17)(-1.6xx10^(-19))=+0.08C`
