If excess of `AgNO_(3)` solution is added to 100 mL of a 0.024 M solution of dichlorobis (ethylenediamine ) cobalt (III) chloride , how many moles of AgCl be precipitated ?

Options

A. 0.0012
B. 0.0016
C. 0.0024
D. 0.0048

Answer

C

Explanation

`[CoCl_(2)(en)_(2)]Cl`. One mole complex contain, one mole of ionisation `Cl^(-)`.
One mole of complex = one mole of `Cl^(-)`
`:.` One mole of `AgCl`= One mole of complex`=(100xx0.024)/(1000)=0.0024`.
