The ammonia prepared by treating ammonium sulphate with calcium hydroxide is completely used by $\mathrm{NiCl}_2 .6 \mathrm{H}_2 \mathrm{O}$ to form a stable coordination compound. Assume that both the reactions are $100 \%$ complete. If $1584 \mathrm{~g}$ of ammonium sulphate and $952 \mathrm{~g}$ of $\mathrm{NiCl}_2 \cdot 6 \mathrm{H}_2 \mathrm{O}$ are used in the preparation, the combined weight (in grams) of gypsum and the nickelammonia coordination compound thus produced is $\qquad$ (Atomic weights in $\mathrm{g} \mathrm{mol}^{-1}: \mathrm{H}=1, \mathrm{~N}=14, \mathrm{O}=16, \mathrm{~S}=32, \overline{\mathrm{Cl}=35.5}, \mathrm{Ca}=40, \mathrm{Ni}=59$ )
