A six coordinate complex of formula CrCl₃.6H₂O has green colour. A 0.1 M solution of the complex when treated with excess of AgNO3 gave 28.7 g of white precipitate. What would be the formula of the complex?

[Cr(H₂O)₅Cl]Cl₂.H₂O

Since $0.1M$ complex gives $0.2$ mole $AgCl$ means 2Cl⁻ are ionisable or out of coordination sphere so, complex is [Cr(H_2​O)5​Cl]Cl₂​.H₂​O
