A 0.500 g sample of a BaCl2•2H2O/Na2SO4 salt mixture, when mixed with water,
filtered, and dried, produced 0.225 g of BaSO4. The Na2SO4 was determined to be
the limiting reactant.

calculate the % of Na2So4 and BaCl2.2hro in the salt solution
Convert grams BaSO4 ppt to g Na2SO4.
moles BaSO4 = grams/molar mass
moles Na2SO4 = moles BaSO4.
grams Na2SO4 = moles Na2SO4 x molar mass Na2SO4.
%Na2SO4 = (mass Na2SO4/mass sample)*100=?
moles BaSO4 = grams/molar mass
moles Na2SO4 = moles BaSO4.
grams Na2SO4 = moles Na2SO4 x molar mass Na2SO4.
%Na2SO4 = (mass Na2SO4/mass sample)*100=?
