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)

Text Solution

Verified by Experts

The correct Answer is:
2992
`underset(=12mol)underset(1584g)((NH_(4))_(2)SO_(4))+Ca(OH)_(2)rarr underset(12mol)underset("gypsum"(M-172))(CaSO_(4).2H_(2)O)+underset(24 "mole")(2NH_(3))`
`underset(952g=4 mol)(NiCl_(2).6H_(2)O)+underset(24 mol)(6MH_(3)) rarr underset( 4 mol) underset((M= 232))([Ni(NH_(3))_(6)]Cl_(2))+6H_(2)O`
Total mass `=12 xx 172+4 xx 232 = 2992 g`.
