which of the following will have the greatest molar conductance at infinite dilution?
1)Pt(NH3)5Cl]Cl3
2)​Pt(NH3)4Cl2]Cl2  
 3)  Pt(NH3)2Cl4]
4) ​Pt(NH3)6]Cl4
PL EXPLAIN IN DETAIL HOW WE CAN SOLVE THIS PROBLEM?

More the number of ions more will  be the conductance. 
So first calculate the number of ions. Complex is considered as 1 ion and outside number of ions are calculated. 
1)Pt(NH3)5Cl]Cl3   = 42)[Pt(NH3)4Cl2]Cl2    = 3  3)  [Pt(NH3)2Cl4]  =14) [Pt(NH3)6]Cl4  = 5So   [Pt(NH3)6]Cl4  will show more conductance
