Answer»

ANSWER:

EXPLANATION:

Mass of the coin =0.75g

Atomic mass of aluminium 26.98g

Number of Al atoms in the coin,

26.98

6.02×10

×0.75=1.67×10

As charge number (z) Al is 13, each atom of Al CONTAIN 13s protons and 13 electrons. MAGNITUDE of positive and negative charges is one paise coin

=NZe=1.67×10

22 ×13×1.6×10 ^−19

C=3.47×10
