I think the answer might be nuclear physics
Answer:
I'm pretty sure its the one that says very little at the beginning but if I get it wrong I'm sorry
The products will be magnesium phosphate and potassium chloride. You then have to watch a solubility chart to see which one of these is not soluable. In this case it is magnesium phosphate.
Molarity = Moles of solute/ L(liters) of solution
So let's plug in the information.
5.0 moles/10L = 0.5 M
