A) 2.16 g
B) 2.48 g
C) 2.32 g
D) 2.64 g
Correct Answer: A
Solution :
[a] Decomposition of \[A{{g}_{2}}C{{O}_{3}}\]gives silver \[\underset{\begin{smallmatrix} 2\times 267g \\ 2.76g \end{smallmatrix}}{\mathop{2A{{g}_{2}}C{{O}_{3}}}}\,\to \underset{\begin{smallmatrix} 4\times 108g \\ 2.16g \end{smallmatrix}}{\mathop{4Ag+}}\,2C{{O}_{2}}+{{O}_{2}}\]
