If a solution containing 126.27 g of mercury(ii) nitrate is allowed to react completely with a solution containing 17.796 g of s
Sphinxa [80]

The number of solid precipitate that will be formed is  37.08 g

calculation

write the equation for reaction

=Hg(NO3)2 +Na2SO4 = HgSO4(s) +2NaNO3(aq)

find the moles of each reactant

moles ofHg(NO3)2=126.27/324.6= 0.389 moles

moles of Na2SO4=17.796/142=0.125 moles

NaSO4 is the limiting reagent and by use of mole ratio of NaSO4:HgSO4 which is 1:1 therefore the moles of H2SO4 is also= 0.125 moles

mass HgSO4=moles x molar mass

=0.125 x296.65= 37.08g
