DrBob222 · Answer

The sodium sulfate is correctly written as Na2SO4. Na2SO4(aq) + Pb(NO3)2(aq) ==> PbSO4(s) + 2NaNO3(aq)

A 1.146 mixture of the solid salts Na2SO4 and Pb(No3)2 forms an aqueous solutionwith the precipitation of PbSO4. The precipitate was found to weigh 0.672g. The limiting reactant is Na2SO4.
What is the percent by mass of each salt in the mixture?
