307 g of Na3PO4 is mixed with 227 g of CaCl2. The reaction that occurs is given by the unbalanced
chemical equation shown below:
2 Na3PO4 (aq) +3CaCl2 (aq) → Ca3(PO4)2 (s) +6NaCl (aq)
(a) Which reactant is limiting?
(b) How many grams of Ca3(PO4)2 are produced?
(c) If 150. g of Ca3(PO4)2 are recovered on the filter paper, what is the percent yield?
