1.	For `[CrCl_(3).xNH_(3)]`, elevation in `b.pt` of one molal solution is triple of one molal aqueous solution of urea. Assuming `100%` ionisation of complex molecule, calculated the value of `x`.
Answer» `[CrCl_(3). xNH_(3)]` is complex which on `100%` ionisation gives a complex ion and ionised `Cl^(-)` ions. Since `DeltaT_(b)` complex `=3xxDeltaT_(b)` urea Thus complex molecule should furnish three ions. Therefore complex is `[CrCl.xNH_(3)]Cl_(2) rarr [CrCl.xNH_(3)]+2Cl^(-)` Also co-ordination number of `Cr` is six. thus `x=5`
