BMAT 2022 Q 14 electrolysis

[Juliette]

hi
the asnwer is B), how can we solve?
my only idea was to use the molar ratio but i was finding 0,01 moles of Cu and of Cl2 but that can’t be right
with Ag²⁺ + SO4²⁻ + CuCl2 = AgCu +SO4²⁻ + Cl2

hi i just went over it and you went for sulfate and not nitrate that’s -1 and then it makes sense that its B by mole ratios
