Question

15. In 1 g of a solid, there are 5 x 1021 atoms. If one electron
is removed from everyone of 0.01% atoms of the solid, the
charge gained by the solid is:
(electronic charge is 1.6 x 10-19 C)​

Answer 1

Answer:

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.
