Solving a chemistry problem

6. When the surface layer of the zinc coating on the iron is damaged, a corrosion process occurs due to the work of the galvanic pair (-)Zn/Zn2 |H2SO4|(Fe)H2|2H( ) for 48 seconds of operation of this galvanic pair, 550 C of electricity flowed through the external circuit. What mass of Zn dissolved in this case and what volume of hydrogen was released at the iron cathode?
