A 1.50-g mixture of the solid salts Na2SO4(molar mass 142.04 g/mol) and Pb(NO3)2(molar mass 331.20 g/mol) forms an aqueous solution with the precipitation of PbSO4 molar mass 303.26 g mol The precipitate was filtered and dried, and its mass was determined to be 0.392 g.The limiting reactant was determined to be Na2SO4. a. Write the molecular form of the equation for the reaction

  • Chemistry -

    Pb(NO3)2(aq) + Na2SO4(aq) ==> PbSO4(s) + 2NaNO3(aq)
