A gravimetric analysis is done according to the chemical equation below: BaCl2 (aq) + Na2SO4 (aq) -> BaSO4 (s) + 2 NaCl ( aq) If 0.5225 grams BaSO4 is collected as precipitate when BaCl2 solution is reacted with excess Na2SO4solution, how many grams of BaCl2 was present initially? (MW BaSO4 is 233.3, MW BaCl2 is 208.2)
