If 8.5g of pure ammonium phosphate , (NH4)3PO4(s), is dissolved in distilled water to make 400mL of solution, what are the concentrations (in moles per litre) of ions in the solution.

How would I solve this type of stoichiometric problem. I know the steps
Step 1: make the balanced equation and state the givens and unknowns
Step 2: find the moles using c=n/v
Step 3: find the mole ratio
Step 4: find the mass

Please guide me! Thanks!!:) I appreciate your time!
