| We translate the values from given to the SI system:

t = 5 min = 300 s.

The expression for determining the current through the charge is:

I = q / t

The charge is determined from the number of electrons and the elementary charge:

q = N * e, where N is the number of electrons, e is the elementary charge e = 1.602 * 10 ^ -19 C.

Substitute this expression into the current strength:

I = q / t = N * e / t

Let us express N from this expression:

N = I * t / e

Substitute the numbers:

N = I * t / e = 10 * 300 / 1.602 * 10 ^ -19 = 1.87 * 10 ^ 22.

Answer: 1.87 * 10 ^ 22 electrons flow through the metal.
