Could you be a little more specific??
Like perhaps the medium specified or the questions that
you are stuck at....its actually not possible to say like that.

2 Ag2 ( CO3) = 4 Ag + 2 CO2 + O2
Atomic Wt of Ag = 108
So wt of residue = (4 * 108 / 2 * 276 )* 2.76 = 2.16 gms
(Mol wt of silver carbonate is 276 gms)
