40 Solution: The balanced reaction is Pb(NO 3 ) 4 aq 2 Na 2 SO 4 aq Pb SO 4 2 s 4 NaNO 3 aq a. The solubility rules say that Pb SO 4 2 is insoluble. b. The amounts of two reactants are given so this is a limiting reagent problem . If all of the Pb(NO 3 ) 4 reacts the amount of precipitate produced will be moles formula mass grams vol conc formula mass grams 0.414 L 0.165
