2.76 g of `Ag_2CO_3` on being heated yields a residue weighing

A

`2.16 g`

B

`2.48 g`

C

`2.32 g`

D

`2.64 g`

Text Solution

Verified by Experts

The correct Answer is:
A
`Ag_(2) CO_(3) rarr 2 Ag + CO_(2) + (1)/(2) O_(2)`
`276 g Ag_(2) CO_(3)` gives `2 xx 108 = 216 g` residue
`2.76 g Ag CO_(3)` gives `2.16 g` residue (silver)
