The ammonia is prepared by treating ammonium sulphate with calcium hydroxide is completely used by ${NiCl}_{2} \cdot 6{H}_{2}O$ to form a stable coordination compound. Assume that, both the reactions are $100$ completed. If $1584g$ of ammonium sulphate and $952g$ of ${NiCl}_{2} \cdot 6{H}_{2}O$ are used in the preparation, the combined weight (in grams) of gypsum and the nickel ammonia coordination compound produced is ____.

Atomic weights in $g{mol}^{- 1}$:

$H = 1; N = 14O = 16; S = 32Cl = 35 .5 ; Ca = 40Ni = 59$
