Dear Student,

Weigth of Hydrogen gas(H2) liberated = 0
504 gWeight of Copper(Cu) deposited = To be caclulatedEquialent weight of Hydrogen = 1 uEuivalent weight of Cu=31
5 uWe know that:Weight of CuWeight of H2=Eq
 weight of CuEq
 weight of H2Hence, Wt  of Cu0 504=31
51or, Weight of Cu deposited=31 5×0
5041=15 9 gm

Therefore, option (b) is correct

Hope this information clears your doubts about the topic

Keep asking!!
