Given: Charge q= 7coulomb.

To Find: Number of electrons.

Solution:

One coulomb (1 C) is the SI unit of charge. It is also defined as the charge in one Ampere of current flowing for one second.

Now,

An electron carries a charge= 1.6*10^-19 C.(It is for a single electron).

We can also say,

1.6*10^-19 C = 1 electron

1 C = 1/1.6*10^-19 electron

Therefore,

7C =( 1/1.6*10^-19 ) × 7 electron

Therefore, 7C has 4.375 × 10^19 electrons.

Answer:  4.375 × 10^19 electrons.
