since it is one hour I.e = 60minutes converting to seconds 60×60=3600s
•°•
6.5×3600
=23400 I.e 2.34×10^4.........

From Faraday's law, Q = IT
Where Q = charge in columb, I = current, T = time in seconds.
T = 1 * 60 * 60 (converting from hour to second)
I = 6.5A
Q = 6.5*(1*60*60) = 2.34*10^4 columb.

From Faraday's first law of electrolysis which state that the mass of a substance dissolved during electrolysis is directly proportional to the quantity of electricity that passes through the electrolytes Q = It
