What is the total number of ions due to the ionisation of complex `CoCl_3.6H_(2)O` ?

Total number of ions the complex CoCl_3 .6NH_3 gives in water

Total number of ions produced by Tollen's reagent on ionisation are

If H_(2)SO_(4) ionises as H_(2)SO_(4) + 2H_(2)O to 2H_(3)O^(+)+SO_(4)^(2-) , then total number of ions produced by 0.1 Molar and 1 L aqueous H_(2)SO_(4) will be:
