A) A solution was prepared by dissolving 1.113 g of MgCl2 into water and made up to 50.0 ml, calculate the molar concentration of the solution.

Question

B) A 250.0 ml of 0.50 M solution of Na3PO2 solution was prepared by diluting 2.5 M of stock solution. Calculate the volume of stock solution required.
C) Solution in (a) was mixed with 50.0 ml of diluted solution in (b), a white preciptate was formed according to the following unbalanced equation:
MgCl2 + Na3PO4---> Mg3(PO4)2 + NaCl

Calculate the mass of Mg3(PO4)2 formed.

I had done part(A) and (B), but I don't know how to do part (C). Thanks for help
