The ammonia prepared by treating ammonium sulphate with calcium hydroxide is completely used by `"NiCl"_(2).6H_(2)O` to form a stable coordination compound. Assume that both the reactions are `100%` complete. If 1584 g of ammonium sulphate and 952 g of `"NiCl"_(2).6H_(2)O` are used in the preparation, the combined weight (in grams) of gypsum and the nickel- ammonia coordination compound thus produced is ____.
(Atomic weights in g` "mol"^(-1)` : H = 1, N = 14, O = 16, S = 32, Cl = 35.5, Ca = 40, Ni = 59)

Answer

2992 g

Explanation

`{:((NH_(4))_(2)SO_(4) +Ca(OH)_(2)to2NH_(3)+CaSO_(4)*2H_(2)O),((1584)/(132)="12 mol 24 mol 4 mol "),(6NH_(3)+[Ni(H_(2)O)_(6)]Cl_(2)to [Ni(NH_(3))_(6)]Cl_(2)+6H_(2)O),("24 mol 4 mol 4 mol "):} `
As weight in gram = no. of mol `xx` Mol . wt.
Wt. of `CaSO_(4)*2H_(2)O("gypusm") + [Ni(NH_(3))_(6)]Cl_(2)`
`= (12 xx 172 + 4 xx 232 g)`
