A 1.276 g mixture of the solid salts Pd(NO3)2 and Na2SO4 produces an aqueous solution with the precipitation of PbSO4. The precipitate was dried and filtered, and its mass was calculated to be 0.717 G. The limiting reactant was determined to be Pb(NO3)2.
Describe the numbers of mols and grams of Pb(NO3)2 are in the reaction mixture? Calculate the percent by mass of each salt in the mixture?
