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:
B
`{:(underset((1584)/(132)"mol = 12 mol")((NH_(4))_(2)SO_(4))+Ca(OH)_(3)overset(100%)rarr underset("12 mol")underset("(Gypsum)")(CaSO_(4).2H_(2)O)+2NH_(3)),(underset((952)/(238)"mol = 4 mol")(NiCl_(2).6H_(2)O)+6NH_(3)overset(100%)rarr underset("4 mol")([Ni(NH_(3))_(6)]Cl_(2))+6H_(2)O):}`
`{:("Mass of CaSO"_(4).2H_(2)O" (gypsum)"=12xx172g=2064g,"(Molecular mass of "CaSO_(4).2H_(2)=172")"),("Mass of "[Ni(NH_(3))_(6)]Cl_(2)=4xx232g=928g,"(Molecular mass of "[Ni(NH_(3))_(6)]Cl_(2)=232")"),("combined weight (in g) "=2064+928=2992,):}`
