Answer:
Electrochemical reaction at cathode is Ag + e Ag (reduction) m = ZIt I = 2Ag t = 20 x 60s = 1200s It = 2A x 1200S = 2400CRead more on Sarthaks.com - https://www.sarthaks.com/892686/solution-nitrate-electrolysed-minutes-current-amperes-calculate-silver-deposited-cathode

Answer:
2.68
Explanation:
m = ZIT
m = 108/96500× 2 × 30 × 60s
m = 0.00111 × 3600
m = 2.68g
