Hg(NO3)2 +Â Â Na2S ----------------> HgS (s) + 2 NaNO3

324.6gÂ Â Â Â Â Â Â Â Â Â Â 78.04gÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 232.65g

84.670gÂ Â Â Â Â Â Â Â Â Â Â 12.026g

here limiting reagent is Na2S . so the product based on that

mass of precipitate HgS formed = 12.026 x 232.65 / 78.04

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 35.85 g

mass of precipitate HgS formed Â Â = 35.85 g

mercury(II) nitrate consumed = 50.02

mercury(II) nitrate excess will remain after the reaction = 84.670 - 50.02

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 34.649 g
