Question

if 1 gram of solid there are 5 into 10 raise to 21 atoms if one electron is removed from everyone of 0.01% of atoms of the solid charge gained by the solid would be

Answer 1

Number of electrons removed in total=(0.01/100)×5×10^21=5×10^17
Charge on each electron=-1.6×10^-19C
Total charge removed=(5×10^17)×(1.6×10^-19)=-0.08C
Thus charge acquired=+0.08C.
