Answer»

2.16 g
2.48 g
2.64 g
2.32 g

SOLUTION :`2Ag_(2)CO_(3) OVERSET(Delta)(rarr) 4 Ag+2 CO_(2)+O_(2)`
`2xx276 GM""4xx108 gm`
`:' 2xx276 gm` of `Ag_(2)CO_(3)` GIVES `4xx108` gm
`:.` 1 gm of `Ag_(2)CO_(3)` gives `=(4xx108)/(2xx276)`
`:.` 2.76 gm of `Ag_(2)CO_(3)` gives
`(4xx108xx2.76)/(2xx276)=2.16` gm
