A mixture, weighing 6.000 grams, contains 41.50 % Na3PO4 and 58.50 % BaCl2 of the mixture, by weight. When dissolved in water, a precipitate forms via the double displacement reaction:
BaCl2(aq) + Na3PO4(aq) NaCl(aq) + Ba3(PO4)2(s)
If the reaction is quantitative, the yield of the solid barium phosphate should be
