Question

What is the concentration of Agt in a 1.2 x 10-4 solution of Ag2CO3? (To write your answer using scientific notation use 1.0E-1 instead of 1.0 x 10-1)

Answer 1

Answer:

2.4E-4

Explanation:

Hello,

By applying the following mass-mole relationship, the concentration could be computed as follows (assuming molarity as long as it isn't specified), since in the silver carbonate two silver molecules are present:

$[Ag]=1.2x10^{-4}\frac{molAg_2CO_3}{L} *\frac{2mol Ag}{1 mol Ag_2CO_3}=2.4x10^{-4}\frac{mol Ag}{L}$

Best regards.
