Both salts are water-soluble, and after mixing together, they
undergo a double-displacement reaction, and they form sodium
chloride, which is soluble and remains in solution, and calcium
phosphate, which is not soluble in water and precipitates out of
solution. The balanced reaction equation can be given as:
2Na3PO4 Â Â Â Â Â Â +
    3CaCl2
           →
          6NaCl
       +      Â
Ca3(PO4)2 (precipitate)
327.88 g    Â
        332.94
g                      Â
351.0 g       Â
             310.17
g (precipitate)
As from balanced equation:
332.94 g of CaCl2 gives --------- 310.17 g of Ca3(PO4)2 as
precipitate
Then 3.2652 g of CaCl2 will gives------3.2652 X 310.17 /
332.94
= 1012.767084 / 332.94 g of Ca3(PO4)2 as precipitate
= 3.041 g Ca3(PO4)2 as precipitate
