The concentration of [CI-] : 0.617 M

Further explanation

FeCl₃ dissolved in 450 mL of solution(will dissociate )

Reaction

FeCl₃⇒Fe³⁺+3Cl⁻

  • mol FeCl₃(MW=162,2 g/mol)

[tex]\tt \dfrac{15}{162.2}=0.0925[/tex]

  • mol Cl⁻ :

[tex]\tt \dfrac{3}{1}\times 0.0925=0.2775[/tex]

  • molarity of Cl⁻ :

[tex]\tt \dfrac{0.2775}{0.45}=0.617~M[/tex]
