1.	The ammonia prepared by treating ammonium sulphate with calcium hydroxide is completely used by `NiCl_(2), 6H_(2)O` to form a stable coodinate compound. Assume that both the reaction are 100% complete. If 1584g of ammonium sulphate and 952g of `NiCl_(2). 6H_(2)O` are used in the preaparation the combined weight (in grams) of gypsum and the nickel-ammonia coordination compound thus produced is Atomic weight is `g mol^(-1): H-1, N=14, O=16, S=32, Cl=35.5, Ca=40, Ni=59)`
Answer» Reaction involved are: `(NH_(4))_(2)SO_(4)+Ca(OH)_(2) to CaSO_(4).2H_(2)O+2NH_(3)` Number of moles of `(NH_(4))_(2)SO_(4)=(1584)/(132)=12` `therefore n_(NH_(3))=24"mol" , n_(CaSO_(4).H_(2)O)=12,` `n_(NiCl_(2).6H_(2)O)=(952)/(238)=4` `underset(4"mol")(NiCl_(2).6H_(2)O)+underset(24"mol")(6NH_(3)) to underset(4"mol")([Ni(NH_(3))_(6)]Cl_(2))+6H_(2)O` `=(12xx172)+(4xx232)` =2992g
