Hello,
In this case, the molecular chemical reaction is:

Thus, by considering the ionic species we have:

Wherein the ammonium and bromide ions are spectator ions since nickel (II) phosphate is largely insoluble in water, therefore, the net ionic equation is:

Best regards.
Answer:
The volume for a piece of gold that has the mass of 318,67 g is 16,50cm3
