It means first we need to check what type of ligand it is then only we can state that what's its coordination number can be

Expert Answer:

Coordination  number depends on type of ligands that are attached to centrral metal atom.
For example, a monodentate ligand contributes to 1 in corrdination number and bidentate ligand contributes to 2 in coordination number.
So we need to check type of ligand to find out coordination number.
