Final answer:
To find the concentrations of NH4⁺ and PO4³⁻ ions in the solution, calculate the number of moles of (NH4)3PO4 and then determine the molar concentration of each ion.
Step-by-step explanation:
To find the concentration of NH4⁺ ions in the solution, we first need to calculate the number of moles of (NH4)3PO4. This can be done using the given mass and the molar mass of (NH4)3PO4.
Number of moles = mass / molar mass
Next, we need to calculate the concentration of NH4⁺ ions in the solution. Since (NH4)3PO4 dissociates into 3 NH4⁺ ions for every 1 (NH4)3PO4, the concentration of NH4⁺ ions is three times the molar concentration of (NH4)3PO4.
Finally, to find the concentration of PO4³⁻ ions, we use the same approach. Since (NH4)3PO4 dissociates into 1 PO4³⁻ ion for every 1 (NH4)3PO4, the concentration of PO4³⁻ ions is the same as the molar concentration of (NH4)3PO4.
