Answer: 
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as 
The equation for the ionization of magnesium phosphate is given as:
When the solubility of 
is S moles/liter, then the solubility of 
will be 3S moles\liter and solubility of 
will be 2S moles/liter.
Thus S = 0.173 g/L or
