John the chemist is trying to make Mg3(PO4)2. He is doing this via the following unbalanced precipitation reaction.
K3PO4(aq) + MgCl2(aq)  Mg3(PO4)2(s) + KCl(aq)
John needs to make ¾ of a kg of Mg3(PO4)2. If he starts with 1500.mL of a 4.711 M solution of K3PO4 and 3500. ML of a solution with 325.72g of MgCl2 dissolved per Liter of solution. Will he be able to make at least ¾ of a kg of Mg3(PO4)2? How much of the product will precipitate out?

A. no, 467.2g B. no, 380.0g C.yes, 1.049kg D. yes, 750.0g E. yes, 928.6g
