`Ba^(2+)` ions, `CN^(-) & Co^(2+)` ions form a water soluble complex with `Ba^(2+)` ions as free cations for a `0.01M` solution of this complex, osmotic pressure `=0.984` atm `&` degree of dissociation `=75%`. Then find ccordination number of `Co^(2+)` ion in this complex (`T=300K, R=0.082L "mol"^(-1) K^(-1)`)
