2.76 g of silver carbonate on being strongly heated yields a residue weighing

Question

2.76 g of silver carbonate on being strongly heated yields a residue weighing (A) 2.16 g (B) 2.48 g (C) 2.32 g (D) 2.64 g

Ag 2 CO 3( s ) arrow 2 Ag ( s )+ CO 2( g )+(1/2) O 2( g ) Molecular Weight of Ag 2 CO 3=276 g And, molecular weight of Ag =2 × 108=216 g 276 g of Ag 2 CO 3 give 216 g Ag. Therefore, 2.76 g of Ag 2 CO 3 on heating will give (216/276) × 2.76 g =2.16 g Ag as residue.

2.16 g

2.48 g

2.32 g

2.64 g

<br/>Ag2​CO3​(s)→2Ag(s)+CO2​(g)+21​O2​(g)<br/> Molecular Weight of Ag2​CO3​=276g And, molecular weight of Ag=2×108=216g 276g of Ag2​CO3​ give 216gAg. Therefore, 2.76g of Ag2​CO3​ on heating will give 276216​×2.76g=2.16gAg as residue.
